The masterclock (MCLK) should be synchronized with sampling clock (LRCK). The phase between these clocks does not matter.The frequency of MCLK is detected automatically, and the internal master clock becomes the appropriate frequency.Table 1 shows system clock example.LRCK MCLK (MHz) BICK (MHz)fs 256fs 384fs 512fs 64fs8kHz 2.048 3.072 4.096 0.51211.025kHz 2.8224 4.2336 5.6448 0.705612kHz 3.072 4.608 6.144 0.76816kHz 4.096 6.144 8.192 1.02422.05kHz 5.6448 8.4672 11.2896 1.411224kHz 6.144 9.216 12.288 1.53632kHz 8.192 12.288 16.384 2.04844.1kHz 11.2896 16.9344 22.5792 2.822448kHz 12.288 18.432 24.576 3.072Table 1. System Clock ExampleIn serial mode (P/S pin = “L”), all external clocks (MCLK, BICK and LRCK) should always be present whenever theDAC is in normal operation mode (PMDAC bit = “1”). If these clocks are not provided, the AK4366 may draw excesscurrent and will not operate properly because it utilizes these clocks for internal dynamic refresh of registers. If theexternal clocks are not present, the DAC should be placed in power-down mode (PMDAC bit = “0”). When MCLK isinput with AC coupling, the MCKAC bit should be set to “1”.In parallel mode (P/S pin = “H”), all external clocks (MCLK, BICK and LRCK) should always be present whenever theDAC is in normal operation mode (PDN pin = “H”). If these clocks are not provided, the AK4366 may draw excesscurrent and will not operate properly because it utilizes these clocks for internal dynamic refresh of registers. If theexternal clocks are not present, the DAC should be placed in power-down mode (PDN pin = “L”).For low sampling rates, DR and S/N degrade because of the outband noise. In serial mode (P/S pin = “L”), DR and S/Nare improved by setting DFS1 bit to “1”. Table 2 shows S/N of HP-amp output. When the DFS1 bit is “1”, MCLK needs512fs.S/N (fs=8kHz, A-weighted) DFS1 DFS0 Over Sample Rate fs MCLK HP-amp0 0 64fs 8kHz ∼48kHz256fs/384fs/512fs 56dB Default 0 1 128fs 8kHz ∼24kHz256fs/384fs/512fs 75dB 1 x 256fs 8kHz ∼12kHz512fs 92dB Table 2. Relationship among fs, MCLK frequency and S/N of HP-ampSerial Data InterfaceThe AK4366 interfaces with external system via the SDATA, BICK and LRCK pins. In serial mode (P/S pin = “L”), fivedata formats are available and are selected by setting DIF2, DIF1 and DIF0 bits (Table 3). In parallel mode (P/S pin =“H”), two data formats are available and are selected by setting DIF0 pin (Table 3). Mode 0 is compatible with existing16bit DACs and digital filters. Mode 1 is a 20bit version of Mode 0. Mode 4 is a 24bit version of Mode 0. Mode 2 issimilar to AKM ADCs and many DSP serial ports. Mode 3 is compatible with the I 2S serial data protocol. In Modes 2 and3 with BICK ≥48fs, the following formats are also valid: 16-bit data followed by eight zeros (17th to 24th bits) and 20-bitdata followed by four zeros (21st to 24th bits). In all modes, the serial data is MSB first and 2’s complement format.DIF2 bit DIF1 bit DIF0 bit MODE BICK Figure0 0 0 0: 16bit, LSB justified 32fs ≤ BICK ≤ 64fsFigure 90 0 1 1: 20bit, LSB justified 40fs ≤ BICK ≤ 64fs Figure 100 1 0 2: 24bit, MSB justified 48fs ≤ BICK ≤ 64fsFigure 110 1 1 3: I 2S Compatible BICK=32fs or 48fs ≤ BICK ≤ 64fs Figure 121 0 0 4: 24bit, LSB justified 48fs ≤ BICK ≤ 64fsFigure 10Table 3.

Mode 3 TimingDigital AttenuatorThe AK4366 has a channel-independent digital attenuator (256 levels, 0.5dB step). This digital attenuator is placed before the D/A converter. ATTL/R7-0 bits set the attenuation level (0dB to −127dB or MUTE) for each channel (Table 5). At DATTC bit = “1”, ATTL7-0 bits control both Lch and Rch attenuation levels. At DATTC bit = “0”, ATTL7-0 bits control the Lch level and ATTR7-0 bits control the Rch level. In parallel mode (P/S pin = “H”), digital attenuator is fixed to 0dB. When HPM bit = “1”, (L+R)/2 summation is done after volume control.ATTL7-0AttenuationATTR7-0FFH 0dBFEH −0.5dBFDH −1.0dBFCH −1.5dB: :: :02H −126.5dB01H −127.0dB00H MUTE (−∞) DefaultTable 5. Digital Volume ATT valuesThe ATS bit sets the transition time between set values of ATT7-0 bits as either 1061/fs or 7424/fs (Table 6). When ATS bit = “0”, a soft transition between the set values occurs(1062 levels). It takes 1061/fs (24ms@fs=44.1kHz) from FFH(0dB) to 00H(MUTE). The ATTs are 00H when the PMDAC bit is “0”. When the PMDAC returns to “1”, the ATTs fade to their current value. Digital attenuator is independent of the soft mute function.ATT speedATS0dB to MUTE 1 stepDefault0 1061/fs 4/fs1 7424/fs 29/fsTable 6. Transition time between set values of ATT7-0 bitsSoft MuteSoft mute operation is performed at digital domain. In serial mode (P/S pin = “L”), when the SMUTE bit goes to “1”, the output signal is attenuated by −∞ during ATT_DATA×ATT transition time (Table 6) from the current ATT level. When the SMUTE bit is returned to “0”, the mute is cancelled and the output attenuation gradually changes to the ATT level during ATT_DATA×ATT transition time. If the soft mute is cancelled before attenuating to −∞ after starting the operation, the attenuation is discontinued and returned to ATT level by the same cycle. The soft mute is effective for changing the signal source without stopping the signal transmission. In parallel mode (P/S pin = “H”), soft mute is not available.Attenuation-∞Analog OutputFigure 13. Soft Mute FunctionNotes:(1) ATT_DATA×ATT transition time (Table 6). For example, this time is 3712LRCK cycles (3712/fs) at ATS bit =“1” and ATT_DATA = “128”.(2) The analog output corresponding to the digital input has a group delay, GD.(3) If the soft mute is cancelled before attenuating to −∞ after starting the operation, the attenuation is discontinuedand returned to ATT level by the same cycle.De-emphasis FilterThe AK4366 includes a digital de-emphasis filter (tc = 50/15µs) by IIR filter corresponding to three sampling frequencies (32kHz, 44.1kHz and 48kHz). In serial mode (P/S pin = “L”), the de-emphasis filter is enabled by setting DEM1-0 bits (Table 7).DEM1 bit DEM0 bit De-emphasis0 044.1kHzDefault0 1 OFF48kHz1 01 132kHzTable 7.

De-emphasis Filter Frequency Select (Parallel Mode)Bass Boost FunctionIn serial mode (P/S pin = “L”), the low frequency boost signal can be output from DAC by controlling BST1-0 bits (Table 9).

Low Frequency Boost SelectSystem ResetThe AK4366 should be reset once by bringing PDN “L” upon power-up.In serial mode (P/S pin = “L”), after exiting reset, VCOM, DAC, HPL and HPR switch to the power-down state. The contents of the control register are maintained until the reset is done. DAC exits reset and power down state by MCLK after PMDAC bit is changed to “1”, and then DAC is powered up and the internal timing starts clocking by LRCK “↑”. DAC is in power-down mode until MCLK and LRCK are input.In parallel mode (P/S pin = “H”), VCOM and DAC are powered up by PDN pin “H”. Headphone amp is powered up by MUTEN pin “H”. DAC exits reset and power down state by MCLK after PDN pin goes to “H”, and then DAC is powered up and the internal timing starts clocking by LRCK “↑”. DAC is in power-down mode until MCLK and LRCK are input.Headphone OutputPower supply voltage for the Headphone-amp is supplied from the HVDD pin and centered on the 0.45 x VDD voltage.The Headphone-amp output load resistance is min.16Ω.1) Parallel mode (P/S pin = “H”)When MUTEN pin is set to “H” at PDN pin = “H”, common voltage goes to 0.45 x VDD. When MUTEN pin is set to “L”,common voltage goes to VSS, and the outputs (HPL and HPR pins) are VSS. When PDN pin is “L”, headphoneamplifiers are powered-down perfectly, and the outputs (HPL and HPR pins) are VSS.2) Serial mode (P/S pin = “L”)When the MUTEN bit is “1” at PMHPL=PMHPR= “1”, the common voltage rises to 0.45 x VDD. When the MUTEN bitis “0”, the common voltage of Headphone-amp falls and the outputs (HPL and HPR pins) go to VSS. When PMHPL andPMHPR bits are “0”, the Headphone-amps are powered-down perfectly, and the outputs (HPL and HPR pins) are VSS.A capacitor between the MUTET pin and ground reduces pop noise at power-up/down. It isrecommended that the capacitor with small variation of capacitance and low ESR (Equivalent SeriesResistance) over all temperature range, since the rise and fall time in Table 10 depend on thecapacitance and ESR of the external capacitor at MUTET pin.t r : Rise Time up to VCOM/2 100k x C (typ)t f : Fall Time down to 0V 200k x C (typ)Table 10.

Power-up/Power-down Timing for Headphone-amp(1) Headphone-amp power-up (PMHPL and PMHPR bits = “1”). The outputs are still VSS.(2) Headphone-amp common voltage rise up (MUTEN bit = “1”). Common voltage of Headphone-amp is rising. This risetime depends on the capacitor value connected with the MUTET pin. The rise time up to VCOM/2 is t r = 100k x C(typ)when the capacitor value on MUTET pin is “C”.(3) Headphone-amp common voltage fall down (MUTEN bit = “0”). Common voltage of Headphone-amp is falling toVSS. This fall time depends on the capacitor value connected with the MUTET pin. The fall time down to 0V is t f =200k x C(typ) when the capacitor value on MUTET pin is “C”.(4) Headphone-amp power-down (PMHPL, PMHPR bits = “0”). The outputs are VSS. If the power supply is switched offor Headphone-amp is powered-down before the common voltage goes to VSS, some pop noise occurs.The cut-off frequency of Headphone-amp output depends on the external resistor and capacitor used. Table 11 shows thecut off frequency and the output power for various resistor/capacitor combinations. The headphone impedance R L is 16Ω.Output powers are shown at HVDD = 2.4, 3.0 and 3.3V. The output voltage of headphone is 0.47 x VDD (Vpp)@−4.8dBFS.Figure 15.

The rise time up to VCOM/2 ist r = 100k x C(typ). When C=1µF, time constant is 100ms(typ).(7) Fall time of headphone amp is determined by external capacitor (C) of MUTET pin. The fall time down to 0V is t f =200k x C(typ). When C=1µF, time constant is 200ms(typ).PMHPL, PMHPR, DACL and DACR bits should be changed to “0” after HPL and HPR pins go to VSS. (8) Analog output corresponding to digital input has the group delay (GD) of 20.8/fs(=472µs@fs=44.1kHz). (9) ATS bit sets transition time of digital attenuator. Default value is 1061/fs(=24ms@fs=44.1kHz).(10) Power supply should be switched off after headphone amp is powered down (HPL/R pins become “L”).Mode Control InterfaceSome function of AK4366 can be controlled by both pins (parallel control mode) and register (serial control mode) shown in Table 12. The serial control interface is enabled by the P/S pin = “L”. Internal registers may be written by 3-wire µP interface pins: CSN, CCLK and CDTI. The data on this interface consists of Chip Address (2bits, fixed to “01”), Read/Write (1bit; fixed to “1”, Write only), Register Address (MSB first, 5bits) and Control Data (MSB first, 8bits). AK4366 latches the data on the rising edge of CCLK, so data should clocked in on the falling edge. The writing of data becomes valid by 16th CCLK “↑”. The clock speed of CCLK is 5MHz (max).Function Parallel mode Serial mode De-emphasis 44.1kHz 32kHz/44.1kHz/48kHz SMUTE Not Available Available Audio I/F Format I2S, Left justified I2S, Left Justified, Right justified Digital Attenuator Not Available Available Bass Boost Not Available Available Power Management Not Available AvailableDefault State at PDN pin = “L” → “H”Power up Power downTable 12.

TP4313_DB1_V1.0
概述TP4313是一款专为小体积移动电源设计的同步单芯片解决方案,内部集成了充电管理单元、放电管理单元、各种保护单元、电量检测及LED指示单元；本方案充电电流为0.7A，放电输出为5V/0.7A，具有低成本、高效率的竞争优势。
方案特性◆独立的充电与放电状态指示◆支持双灯与单灯模式◆放电效率：90%（输入3.7V，输出5V/0.7A）◆充电电流: 0.7A◆输出电流：5V/0.7A◆BAT放电终止电压:2.85V◆可选4.2V/4.35V充电电压◆最大20uA待机电流◆集成充电管理与放电管理◆智能温度控制◆集成输出过压保护、短路保护、重载保护◆集成过充与过放保护◆支持涓流模式以及零电压充电◆封装形式： SOP8L应用电路芯片管脚ESOP8L应用关键点1、 5V输出端的USB外壳不能接GND，需浮空；2、电阻R1对封装无要求，但是R1不能省略；3、输出D+/D-若不加分压电阻则需要短接，否则对某些品牌手机不能充电（比如苹果）；如果加分压电阻，则需保证分压电阻的总等效电阻至少为OUTN等效电阻的6倍以上，否则插入负载时不能自动识别；OUTN默认电阻为50K，可以在OUTN于GND并联电阻以减小OUTN的总等效电阻；4、输出电容C2选择低ESR的贴片电容,否则会影响输出纹波；5、电感L1的饱和电流需大于2.5A，否则因电感饱和可能会导致芯片工作不正常；6、 TP4313集成了过充保护、过放保护、过温保护、输出过压保护、输出重载保护、输出短路保护等多重保护机制，也可以额外再加一颗DW01对系统进行双重保护；7、充电时，LED1以1Hz频率闪烁，电池充饱后LED1常亮；放电时，LED2常亮，放电结束后LED2熄灭；8、对于可以用一颗LED灯的模具，TP4313也可以只用一颗LED同时实现充电与放电指示，只需将芯片的LED1与LED2短接后再接LED灯，充电放电指示方式与以上一样，只是用同一颗灯实现而已。
PCB设计参考1、5V输出端的USB外壳不能接GND，需浮空；2、整个PCB建议敷铜散热，散热面积尽量大；3、BAT与地的电容C3靠近IC的BAT 和GND脚，BAT+和BAT-需先经过BAT电容再到IC，各GND走线要尽量粗，空余的地方全部走GND；。

SilverStone GEMINI ST46GF 460W + 460W 双重冗余电源说明书
SPECIFICATIONSilverStone GEMINI ST46GFMini Redundant Power SupplyWith Active PFC460W + 460W1. GeneralThis is the specification of Model SST-ST46GF; it is intended to describe the functionsand performance of the subject power supply. This 460 watts Redundant Power Supplywith Active PFC (Power Factor Correction) capability, meets EN61000-3-2 and equipsFull Range Input features.2. AC Input Characteristics2.1 AC Input Voltage, Frequency and Current ( Rating: 100V-240Vac, 47-63Hz, 8-4A )The power supply must operate within all specified limits over the input voltage range in Table 1.Harmonics distortion of up to 10% THD must not cause the power supply to go out of specified limits.Table 1 - AC Input Voltage and Frequency2.2 AC Inrush CurrentThe power supply must meets inrush requirements of any rated AC voltage, during turn on at anyphase of voltage, during a single cycle AC dropout condition, during repetitive On/Off cycling ofAC, and over the specified temperature range. The peak inrush current shall be less than the ratingof its critical components (including input fuse, bulk rectifiers, and surge limiting device).012.3 Input Power Factor Correction ( Active PFC)>_The power factor at full load shall be 0.98 at nominal input voltage.2.4 Input Current HarmonicsWhen the power supply is operated in 90-264Vac of Sec. 2.1, the input harmonic current drawn on the power line shall not exceed the limits set by EN61000-3-2 class “D” standards. The power supply shall incorporate universal power input with active power factor correction.2.5 AC Line DropoutAn AC line dropout of 17mS or less shall not cause any tripping of control signals or protection circuits. If the AC dropout lasts longer than 17mS the power supply should recover and meet all turn on requirements. The power supply shall meet the regulation requirement over all rated AC voltages, frequencies, and output loading conditions. Any dropout of the AC line shall not cause damage to the power supply. An AC line dropout is defined as a drop in AC line to 0VAC at any phase of the AC line for any length of time.023. DC Output Specification3.1 Output Current / LoadingThe following table defines power and current rating. The power supply shall meetboth static and dynamic voltage regulation requirements for minimum load condition.Table 2– Output Loads Range 1:Note 1: Maximum continuous total DC output power should not exceed 460 W.3.2 DC Voltage Regulation, Ripple and NoiseThe power supply output voltages must stay within the following voltage limits whenoperating at steady state and dynamic loading conditions. All outputs are measuredwith reference to the return remote sense (ReturnS) signal. The +5V,+3.3V, +12V,-5V,-12V and +5VSB outputs are measure at the power supply connectors referencesto ReturnS. The +5V and +3.3V is measured at its remote sense signal (+5VS, +3.3VS)located at the signal connector.Table 3 – Regulation, ripple and noiseRipple and Noise shall be measured using the following methods:a) Measurements made differentially to eliminate common-mode noiseb) Ground lead length of oscilloscope probe shall be ? 0.25 inch.c) Measurements made where the cable connectors attach to the load.d) Outputs bypassed at the point of measurement with a parallel combination of10uF tantalum capacitor in parallel with a 0.1uF ceramic capacitors.e) Oscilloscope bandwidth of 0 Hz to 20MHz.f) Measurements measured at locations where remote sense wires are connected.g) Regulation tolerance shall include temperature change, warm up drift and dynamic load. 03These are the timing requirements for the power assembly operation. The output voltages must rise from 10% to within regulation limits (Tvout_rise) within 5 to 70mS. The +5V, +3.3V and +12V output voltages should start to rise at about the same time. All outputs must rise monotonically. The +5V output needs to be greater than the +3.3V output during any point of the voltage rise.The +5V output must never be greater than the +3.3V output by more than 2.25V. Each output voltage shall reach regulation within 50 mS (Tvout_on) of each other during turn on of the power supply. Each output voltage shall fall out of regulation within 400 mS (Tvout_off) of each other during turn off. Figure 1 and figure 2 show the turn On and turn Off timing requirement. In Figure 2, the timing is shown with both AC and PSON# controlling the On/Off of the power supply.Table 4 – Output Voltage TimingFigure 1 : Output Voltage Timing043. DC Output Specification3.1 Output Current / LoadingThe following table defines power and current rating. The power supply shall meetboth static and dynamic voltage regulation requirements for minimum load condition.Table 5 – Turn On/Off TimingFigure 2 : Turn On/Off Timing05The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on the +5V, +3.3V, +12V,-5V and -12V power rails. When this signal is not pulled low by the system, or left open, the outputs (except the +5VSB and V bias) turn off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply.Table 6 – PWOK Signal Characteristic3.5 EfficiencyThe efficiency is 68% at full loading condition to help reduce system power consumption attypical system loading conditions.3.6 +5VSB (Standby)The +5VSB output is always on (+5V Standby) when AC power is applied and power switch is turned on.The +5VSB line is capable of delivering at a maximum of 2A for PC board circuit to operate.4. ProtectionProtection circuits inside the power supply shall cause only the power supply’s main outputs to shutdown. If the power supply latches off due to a protection circuit tripping, either a AC cycle OFF for 15 sec, or PSON# cycle HIGH for 1 sec must be able to restart the power supply.4.1 Over Power ProtectionThe OPP function shall work at 130%~270% of rating of output power (when optional external protect card is not present), then all outputs shut down in a latch off mode.The latch shall be cleared by toggling the PSON# signal or by cycling the AC power.The power supply shall not be damaged from repeated power cycling in this condition.If only one module works inside the power supply, the OPP is at 110%~170% of ratingof power supply.4.2 Over Voltage ProtectionEach hot swap module has respective OVP circuit. Once any power supply module shut down ina latch off mode while the output voltage exceeds the over voltage limit shown in Table 7, the othermodules should deliver the sufficient power to the device continually.06Table 7 –Over Voltage protection4.3 Over Current ProtectionThe power supply should contain the OCP function on each hot swap module.The power supply should be shut down in a latch off mode while the respective output currentexceeds the limit as shown in Table 8. When the latch has been cleared by toggling the PSON# single or cycling the AC input power. The power supply module should not be damaged in this condition.Table 8 –Over Current protection4.4 Short Circuit ProtectionThe power supply shall shut down in a latch off mode when the output voltage is short circuit.5. Environmental Requirements5.1 Temperature076. Agency Requirements6.1 Safety Certification.Table 8 –Safety Certification6.2 AC Input Leakage CurrentInput leakage current from line to ground will be less than 3.5mA rms. Measurement will be made at 240 VAC and 60Hz.7. Redundant Power Supply Function7.1 RedundancyThe redundant power supply is N+1=N (460W+460W=460W) function power supply, each one module is redundancy when any one module was failed. To be redundant each item must be in the Hot swap power supply module.087.2 Hot Swap RequirementsThe redundant power supply modules shall be hot swappable. Hot swapping a power supply is the process of inserting and extracting a power supply from an operating. During this process the output voltage shall remain within the limits specified in Table 7 with the capacitive load specified Table 9. The Sub-system shall not exceed the maximum inrush current as specified in section 2.2. The power supply can be hot swapped by the following methods:7.3 LED IndicatorsThere shell be a single bi-color LED.The GREEN LED shall turn ON to indicate that all the power outputs are available.The Red LED shall turn ON to indicate that the power supply has failed, shutdown due to over current, or shutdown due to component failure.The LED(s) shall be visible on the power supply’s exterior face. The LED location shall meet ESD requirements.LED shall be securely mounted in such a way that incidental pressure on the LED shall not cause it to become displaced.Many variations of the above are possible. Supplies need to be compatible with these different variations depending upon the sub-system construction. In general, a failed (off by internal latch or external control) supply may be removed, then replaced with a good power supply(must use the same model) , however, hot swap needs to work with operational as well as failed power supplies. The newly inserted power supply may get turned on by inserting the supply into the system or by system management recognizing an inserted supply and explicitly turning it on.AC connecting separately to each module. Up to two power supplies may be on a single AC power source.Extraction: The AC power will be disconnected from the power supply first and then thepower supply is extracted from the sub-system. This could occur in standby mode or powered on mode. Insertion: The module is inserted into the cage and then AC power will be connected to the power supply module.●For power modules with AC docking at the same time as DC. Extraction: The module is extracted from the cage and both AC and DC disconnect at the same Time. This could occur in standby or power on mode. No damage or arcing shall occur to the DC or AC contactswhich could cause damage. Insertion: The AC and DC connect at the same time as the module is inserted into the cage. No damage to the connector contacts shall occur. The module may power on or come up into standby mode.●098. Reliability8.1 Mean Time Between Failures (MTBF)The MTBF of the power supply shall be calculated utilizing the Part-Stress Analysis method of MIL217F or Bell core RPP. The calculated MTBF of the power supply shall be greater than100,000 hours under the following conditions:Full rated load120V AC inputGround Benign25°C9.

TP4366 内部集成了温度反馈环路，工作时，如果芯片内 部的温度升高到 120℃(表面 80℃左右)， 充电或放电电流 会随着芯片的温度升高而降低，从而减小系统功耗，降 低温升，由于温度反馈控制，IC 会进入恒温模式而不用 担心损坏 IC 或者过高温度时强行关闭 IC。

元件选择
1、输出电容 C1 选择质量较好的低 ESR 的贴片电容,否 则会影响输出纹波； 2、电感 L1 的饱和电流需大于 3A，否则因电感饱和可能 会导致芯片工作不正常；
PCB 设计参考
1、IC 下面敷铜接 GND，地线铺开面积要尽量大，其它 不重要的线都可以绕开以满足地线需要； 2、 建议电感旁边放置 10uF 而靠近芯片 BAT 脚放置 1uF 电容；如果只放一个 BAT 电容，必须保证电容位置既要 靠近芯片又要靠近电感；电容的地线尽量接在大面积地 线上，不要经过较小的地线再到芯片和大面积地； 3、输出电容 C1 尽量靠近芯片，其地线尽量接在大面积 地线上，不要经过较小的地线再到芯片和大面积地； 4、电感需靠近 BAT 电容，电感和 BAT 电容 C2 以及芯 片尽量在同一层而不要过过孔，电感到 SW 的走线尽量 短而粗；
手电照明输出
SWT 端可以驱动 LED 灯用于手电筒照明,最大驱动电流 为 50mA , 可以给 LED 串联电阻来减小指示手电灯的电 流， SWT 同时也是按键开关脚， 如果长按 S1 键 2S,手电 筒打开，再次长按 S1 键 2，当 BAT 电压大于 3.2V 时,升压电路开始工作， 工作过程中如果电池电压低于 3.0V，则 LED1 会以 2HZ 频率快闪提醒电量较低， 当电池电压低于 2.85V， 则放电 输出关闭，TP4366 进入低电流待机模式。
充电模式
如果充电之前锂离子电池电压低于 2.9V， 为了保护电池， TP4366 工作在涓流充电模式， 此时充电电流为 100mA； 当电池电压达到 2.9V 以后， TP4366 进入恒流充电模式， 充电电流为 1A；当电池电压达到 4.2V 后，TP4366 工作 在恒压充电模式，此时 BAT 电压恒定，充电电流逐渐减 小，当充电电流减小为 100mA 时，充电过程结束，充电 电流降为零。
