These levels can be altered by using the control voltage(CONT)terminal.When the trigger input falls below trigger level,the flip-flop is set and the output goes high.If the trigger input is above the trigger level and the threshold input is above the threshold level,the flip-flop is reset,and the output is low.The reset(RESET)input can override all other inputs and can be used to initiate a new timing cycle.When RESET goes low,the flip-flop is reset and the output goes low.When the output is low,a low-impedance path is provided between the discharge(DISCH)terminal and ground(GND).Please be aware that an important notice concerning availability,standard warranty,and use in critical applications of TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.GNDRESET can override TRIG,which can override THRES.NA556,NE556,SA556,SE556DUAL PRECISION TIMERSSLFS023G–APRIL 1978–REVISED JUNE 2006ORDERING INFORMATIONV T (MAX)T APACKAGE (1)ORDERABLE

SG3525工作原理以及输出电路驱动电路
SG3525工作原理以及输出电路驱动电路SG3525内部包含一个误差放大器、一个PWM比较器、一个控制逻辑单元和多个驱动电路。
误差放大器用于将参考电压（通常通过一个电位器调节）与反馈电压进行比较，并产生误差信号。
PWM比较器通过与误差放大器相关联的控制逻辑单元来产生脉宽调制信号。
驱动电路用于将脉宽调制信号转换为驱动信号，并控制开关管的开关状态。
当输入电压超过参考电压时，误差放大器会产生一个正偏差信号，反之则产生负偏差信号。
这个偏差信号经过PWM比较器和控制逻辑单元的处理后，产生一个脉宽比例。
脉宽比例表示开关管导通和截止的时间比例，通过调节脉宽比例，可以控制开关管的导通和截止时间，进而控制输出电压。
SG3525的输出电路通常由开关管、滤波电容和负载组成。
驱动电路的输出信号直接控制开关管的导通和截止。
当开关管导通时，输入电压通过开关管和滤波电容传递到负载，负载接收到电压。
当开关管截止时，输入电压无法通过开关管传递到负载，负载不接收电压。
总结起来，SG3525的工作原理是通过脉宽调制控制开关管的导通和截止，从而调节输出电压。
输出电路由开关管、滤波电容和负载组成，驱动电路由晶体管组成，控制开关管的开关状态。
这种工作原理和输出电路驱动电路的设计使得SG3525广泛应用于直流电源、逆变器、电机驱动等领域。

Si51211数据手册：三输出工厂可编程时钟生成器说明书
Si51211 Data SheetThree Output Factory Programmable Clock GeneratorThe factory programmable Si51211 is a low power, small footprint and frequency flexible programmable clock generator targeting low power, low cost and high volume consumer and embedded applications. The device operates from a single crystal or an external clock source and generates 1 to 3 outputs up to 170 MHz. The device is factory pro-grammed to provide customized output frequencies and control input such as frequency select, spread spectrum on, power down and output enable. Center spread spectrum can also be programmed to reduce EMI to meet board level system requirements.KEY FEATURES•Generates up to 3 CMOS clock outputs from 3 to 170 MHz•Accepts crystal or reference clock input •3 to 165 MHz reference clock input •8 to 48 MHz crystal input•Programmable FSEL, SSONb, PD, and OE input functionsApplications•Crystal/XO replacement •EMI reduction •Portable devices•Digital still camera •IP phone •Smart meterXIN/CLKINXOUT VDD VSS VDDO1. Feature ListThe Si51211 highlighted features are listed below.•Generates up to 3 CMOS clock outputs from 3 to 170 MHz •Accepts crystal or reference clock input• 3 to 165 MHz reference clock input•8 to 48 MHz crystal input•Programmable FSEL, SSONb, PD, and OE input functions •Low power dissipation •Separate voltage supply pins•V DD = 2.5 to 3.3 V•V DDO = 1.8 to 3.3 V (V DDO < V DD)•±0.25%, ±0.5% or ±1% spread spectrum (center spread)•Low cycle-cycle jitter•Ultra small 8-pin TDFN package (1.4 mm x 1.6 mm)Si51211 Data Sheet • Feature List2. Design Considerations2.1 Typical Application Schematic2.2 Comments and RecommendationsDecoupling Capacitor: A decoupling capacitor of 0.1 μF must be used between VDD and VSS on pins 1 and 8. Place the capacitor on the component side of the PCB as close to the VDD pin as possible. The PCB trace to the VDD pin and to the GND via should be kept as short as possible. Do not use vias between the decoupling capacitor and the VDD pin. In addition, a 10 µF capacitor should be placed between VDD and VSS.Series Termination Resistor: A series termination resistor is recommended if the distance between the outputs (SSCLK or REFCLK pins) and the load is over 1 ½ inches. The nominal impedance of the SSCLK output is about 30 Ω. Use a 20 Ω resistor in series with the output to terminate a 50 Ω trace impedance and place a 20 Ω resistor as close to the SSCLK output as possible.Crystal and Crystal Load: Only use a parallel resonant fundamental AT cut crystal. Do not use higher overtone crystals. To meet the crystal initial accuracy specification (in ppm) make sure that the external crystal load capacitor is matched to the crystal load specification. To determine the value of CL1 and CL2, use the following formula:CL1 =CL2 = 2CL−Cpin +Cp;where CL is the load capacitance stated by the crystal manufacturer,Cpin is the Si51211 pin capacitance (3 pF), andCp is the parasitic capacitance of the PCB traces.Example: If a crystal with CL = 12 pF specification is used and Cp = 1 pF (parasitic PCB capacitance on PCB), 19 or 20 pF external capacitors from pins XIN (pin 2) and XOUT (Pin 3) to VSS are required. Users must verify Cp value.Table 2.1. Crystal Specifications3. Electrical SpecificationsTable 3.1.

AC Electrical Specifications (V DD = 2.5 V ±10%, or V DD = 3.3 V ±10%, V DDO = V DD, C L = 10 pF, T A = –40 to 85 °C)Table 3.3. Absolute Maximum Conditions4. Functional Description4.1 Input Frequency RangeThe input frequency range is from 8.0 to 48.0 MHz for crystals and ceramic resonators. If an external clock is used, the input frequency range is from 3.0 to 165.0 MHz.4.2 Output Frequency Range and OutputsUp to three outputs can be programmed as SSCLK or REFCLK. SSCLK output can be synthesized to any value from 3 to 170 MHz with spread based on valid input frequency. The spread at the SSCLK pins can be enabled or disabled by the SSONb input control pin. If SSONb is used, when this pin is pulled high (V DD), the frequency at SSCLK pin is synthesized to the nominal value of the input frequency without spread. If low (GND), the frequency at SSCLK is synthesized to the nominal value of the input frequency with spread..REFCLK is the buffered output of the oscillator and is the same frequency as the input frequency without spread. By using only low cost, fundamental mode crystals, the Si51211 can synthesize output frequency up to 170 MHz, eliminating the need for higher order crystals (Xtals) and crystal oscillators (XOs). This reduces the cost while improving the system clock accuracy, performance, and reliability.4.3 Programmable Spread Percent (%)The spread percent (%) value is programmable to ±0.25%, ±0.5% or ±1% (center spread) for all SSCLK frequencies.4.4 SSONb or Frequency Select (FSEL)The Si51211 pins 4 and 6 can be programmed as SSONb to enable or disable the programmed spread percent value. If SSONb is used, when this pin is pulled high (V DD),the frequency at SSCLK pin is synthesized to the nominal value of the input frequency without spread. If low (GND), the frequency at SSCLK is synthesized to the nominal value of the input frequency with spread. Pin 4 can also be programmed as frequency select (FSEL) function.If FSEL function is used, the output pin can be programmed for different set of frequencies as selected by FSEL. SSCLK value can be any frequency from 3 to up to 170 MHz, but the spread % is the same percent value. REFCLK is the same frequency as the input reference clock. The set of frequencies in the table below are given as an example, using a 48 MHz crystal.Table 4.1. Example Frequencies4.5 Power Down (PD) or Output Enable (OE)The Si51211 pin 6 can be programmed as PD input. Pin 4 and pin 6 can be programmed as OE input. PD turns off both PLL and output buffers whereas OE only disables the output buffers to Hi-Z. The OE function is asynchronous. Any requirement for synchronous operations (like glitchless output clock switching) needs to be handled externally.5.

• Fast PWM Converter Transient Response
• Under and Overvoltage Monitoring on All Outputs
• OCP on the Switching Regulator
• Integrated Thermal Shutdown Protection
The switching PWM controller drives two N-Channel MOSFETs in a synchronous-rectified buck converter topology. The synchronous buck converter uses voltagemode control with fast transient response. Both the switching regulator and standby LDO provide a maximum static regulation tolerance of ±2% over line, load, and temperature ranges. The output is user-adjustable by means of external resistors down to 0.8V.
