在各种音源共存的时代，组建一套音响系统，CD机或许是标配的音源。

而在策划本特辑时，我们发现这两三年内测试过的CD机数量并不少，在此挑选出不同价位、功能各异的11台CD机与大家分享，希望有需要的朋友从中觅得所爱。

7SPECIAL HEPQHT 特辑| 11台CD 播放机简评关于机芯在入门级的CD 机中，三洋的机芯组件是最常见的，后期若有故障要更换零件的话，也是很方便的，其光头的寿命也不差。

而曾经广泛被各大厂家使用的飞利浦机芯早已退出市场，其著名的CDPR 0系列机芯目前也难觅踪影了，但是飞利浦的伺服芯片仍然广泛应用在各种CD 机上。

另外，奥地利Stream Unlimited 出品的机芯，也被一些高端的CD 机所采用。

还有一些品牌采用自己开发的机芯，如本专辑中介绍的Luxman o解码芯片重不重要？CD 机的解码芯片，其任务是对数字信号进行解码，转换为模拟音频信号，因此是比较重要的，但它并非是决定一台CD 机声音优秀与否的条件，君不见一些数千元的CD 机或解码器也采用一些与名机一样的解码芯片吗？但声音表现未必就好，关键还是如何使用的问题。

也有的厂家使用低价的DAC 芯片，声音依然能做到优秀。

LG 液晶电视机 32LS3158-CB 使用说明书

• 建议每年一次联络服务中心清理电视机内部。聚集的灰尘可能引起机械故障。
• 向服务中心要求维修服务。不论电视机因何种方式损坏，如电源线或插头损坏，液体流入或物体落入电视机内，电视机暴露在雨中或潮湿的地方后无法正常使用，电视机跌落，都可以邀请维修。
重要预防措施
7
• 冷机状态下打开电视机时可能会出现些微“闪烁”，这是正常现象，电视机没有故障。
• 长时间显示一个固定图像（如广播频道标识、屏幕菜单、电视游戏场景）可能损伤屏幕，导致图像残留，这就是图像拖尾。图像拖尾不会覆盖在电视机上。避免观看一个固定图像超过一小时。如果长时间使用4：3的画面比率观看电视，面板边缘可能发生图像拖尾。这种现象也可能出现在第三方产品中，不能退换。
• 杂音 “破裂”声：观看电视或关闭电视机时，塑料因为温度和湿度的原因发热收缩从而产生破裂声，这是会发生热变形的产品的普遍现象。电路或面板的“嗡嗡”声：电路高速开关过程中产生的大量电流会导致低频噪音，这种情况因产品不同而有所差异。产生的杂音不影响电视机性能。

Richtek RT7296C 3A 同步步进下降电源说明书

RT7296C 3A, 17V Current Mode Synchronous Step-Down ConverterGeneral DescriptionThe RT7296C is a high-efficiency, 3A current mode synchronous step-down DC/DC converter with a wide input voltage range from 4.5V to 17V. The device integrates 80mΩhigh-side and 30mΩlow-side MOSFETs to achieve high efficiency conversion. The current mode control architecture supports fast transient response and internal compensation. A cycle-by-cycle current limit function provides protection against shorted output. The RT7296C provides complete protection functions such as input under-voltage lockout, output under-voltage protection, over-current protection, and thermal shutdown. The PWM frequency is adjustable by the EN/SYNC pin. The RT7296C is available in the TSOT-23-8 (FC) package. Ordering InformationG : Green (Halogen Free and Pb Free) RT7296CNote :Richtek products are :④RoHS compliant and compatible with the currentrequirements of IPC/JEDEC J-STD-020.④Suitable for use in SnPb or Pb-free soldering processes. Features● 4.5V to 17V Input Voltage Range●3A Output Current●Internal N-Channel MOSFETs●Current Mode Control●Fixed Switching Frequency : 1.4MHz●Synchronous to External Clock : 300kHz to 3MHz ●Cycle-by-Cycle Current Limit●External Soft-Start Function●Input Under-Voltage Lockout●Output Under-Voltage Protection●Thermal ShutdownApplications●Industrial and Commercial Low Power Systems●Computer Peripherals●LCD Monitors and TVs●Set-top BoxesMarking Information00= : Product CodeDNN : Date CodeSimplified Application CircuitEnableOUTV INRT7296CPin ConfigurationsS SS WG N D F BE N /S Y N CB O O TV I NP V C C(TOP VIEW)TSOT-23-8 (FC)Functional Pin DescriptionRT7296CFunction Block DiagramBOOTGNDSWFBOperationUnder Voltage Lockout ThresholdThe IC includes an input Under Voltage Lockout Protection (UVLO). If the input voltage exceeds the UVLO rising threshold voltage (3.9V), the converter resets and prepares the PWM for operation. If the input voltage falls below the UVLO falling threshold voltage (3.25V) during normal operation, the device stops switching. The UVLO rising and falling threshold voltage includes a hysteresis to prevent noise caused reset. Chip EnableThe EN pin is the chip enable input. Pulling the EN pin low (<1.1V) will shutdown the device. During shutdown mode, the RT7296C’s quiescent current drops to lower than 1μA. Driving the EN pin high (>1.6V) will turn on the device.Operating Frequency and SynchronizationThe internal oscillator runs at 1400kHz (typ.) when the EN/SYNC pin is at logic-high level (>1.6V). If the EN pin is pulled to low-level over 8μs, the IC will shut down. The RT7296C can be synchronized with an external clock ranging from 300kHz to 3MHz applied to the EN/SYNC pin. The external clock duty cycle must be from 20% to 80% with logic-high level = 2V and logic-low level = 0.8V. Internal RegulatorThe internal regulator generates 5V power and drive internal circuit. When VIN is below 5V, PVCC will drop with VIN. A capacitor (>0.1μF) between PVCC and GND is required. Soft-Start FunctionThe RT7296C provides external soft-start function. The soft-start function is used to prevent large inrush current while converter is being powered-up. TheRT7296Csoft-start timing can be programmed by the external capacitor between SS pin and GND. The Chip provides a 11μA charge current for the external capacitor. Over Current ProtectionRT7296C provides cycle-by-cycle over current limit protection. When the inductor current peak value reaches current limit, IC will turn off High Side MOS to avoid over current.Under Voltage Protection (Hiccup Mode)RT7296C provides Hiccup Mode of Under Voltage Protection (UVP). When the FB voltage drops below half of the feedback reference voltage, V FB , the UVP function will be triggered and the IC will shut down for a period of time and then recover automatically. The Hiccup Mode of UVP can reduce input current in short-circuit conditions. Thermal ShutdownThermal shutdown is implemented to prevent the chip from operating at excessively high temperatures. When the junction temperature is higher than 150︒C, the chip will shutdown the switching operation. The chip is automaticallyre-enabledwhenthejunctiontemperature cools down by approximately 20︒C.RT7296C Absolute Maximum Ratings(Note 1)●Supply Input Voltage, VIN ----------------------------------------------------------------------------------- -0.3V to 20V●Switch Voltage, SW-------------------------------------------------------------------------------------------- -0.3V to V IN + 0.3V<20ns--------------------------------------------------------------------------------------------------------------- -5V●BOOT to SW, V BOOT – SW ----------------------------------------------------------------------------------- -0.3V to 6V (7V for < 10μs) ●Bias Supply Output, PVCC---------------------------------------------------------------------------------- -0.3V to 6V (7V for < 10μs) ●Other Pins--------------------------------------------------------------------------------------------------------- -0.3V to 6V●Power Dissipation, P D @ T A = 25︒CTSOT-23-8 (FC) ------------------------------------------------------------------------------------------------ 1.428W●Package Thermal Resistance (Note 2)TSOT-23-8 (FC), θJA ----------------------------------------------------------------------------------------- 70︒C/WTSOT-23-8 (FC), θJC ----------------------------------------------------------------------------------------- 15︒C/W●Lead Temperature (Soldering, 10 sec.) ----------------------------------------------------------------- 260︒C●Junction Temperature ----------------------------------------------------------------------------------------- -40︒C to 150︒C●Storage Temperature Range ------------------------------------------------------------------------------- -65︒C to 150︒C●ESD Susceptibility (Note 3)HBM (Human Body Model) --------------------------------------------------------------------------------- 2kV Recommended Operating Conditions(Note 4)●Supply Input Voltage, VIN --------------------------------------------------------------------------------------- 4.5V to 17V●Junction Temperature Range ---------------------------------------------------------------------------------------- -40︒C to 125︒C●Ambient Temperature Range ---------------------------------------------------------------------------------------- -40︒C to 85︒C Electrical Characteristics(V = 12V, T = 25︒C, unless otherwise specified)RT7296Cstress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.

Output Voltage SelectionThe resistive voltage divider allows the FB pin to sense a fraction of the output voltage as shown in Figure 1.OUTFigure 1. Output Voltage SettingFor adjustable voltage mode, the output voltage is set by an external resistive voltage divider according to the following equation :OUT FB R1V V 1R2=+⎛⎫⎪⎝⎭Where V FB is the feedback reference voltage (0.807V typ.). Table 2 lists the recommended resistors value for common output voltages.External Bootstrap DiodeConnect a 100nF low ESR ceramic capacitor between the BOOT pin and SW pin. This capacitor provides the gate driver voltage for the high side MOSFET. It is recommended to add an external bootstrap diode between an external 5V and BOOT pin, as shown as Figure 2, for efficiency improvement when input voltage is lower than 5.5V or duty ratio is higher than 65% .The bootstrap diode can be a low cost one such as IN4148 or BAT54. The external 5V can be a 5V fixed input from system or a 5V output (PVCC) of the RT7296C.Figure 2. External Bootstrap DiodeExternal Soft-Start CapacitorRT7296C provides external soft-start function. The soft-start function is used to prevent large inrushcurrent while converter is being powered-up. The soft-start timing can be programmed by the external capacitor (C SS ) between SS pin and GND. The Chip provides a 11μA charge current (I SS ) for the external capacitor. The soft-start time (t SS , V REF is from 0V to 0.8V) can be calculated by the following formula :SS SS SS C (nF) 1.3t (ms) = I (A)μ⨯Inductor SelectionThe inductor value and operating frequency determine the ripple current according to a specific input and output voltage. The ripple current ∆I L increases with higher VIN and decreases with higher inductance.OUT OUT L IN V VI 1f L V ⎛⎫⎛⎫∆=⨯- ⎪ ⎪⨯⎝⎭⎝⎭Having a lower ripple current reduces not only the ESR losses in the output capacitors but also the outputvoltage ripple. High frequency with small ripple current can achieve highest efficiency operation. However, it requires a large inductor to achieve this goal.For the ripple current selection, the value of ∆I L = 0.3(I MAX ) will be a reasonable starting point. The largest ripple current occurs at the highest V IN . To guarantee that the ripple current stays below the specified maximum, the inductor value should be chosen according to the following equation :OUT OUT L(MAX)IN(MAX)V V L 1f I V ⎛⎫⎛⎫=⨯- ⎪ ⎪ ⎪ ⎪⨯∆⎝⎭⎝⎭RT7296CThe inductor's current rating (caused a 40︒C temperature rising from 25︒C ambient) should be greater than the maximum load current and its saturation current should be greater than the short circuit peak current limit. C IN and C OUT SelectionThe input capacitance, C IN , is needed to filter the trapezoidal current at the source of the top MOSFET. To prevent large ripple current, a low ESR input capacitor sized for the maximum RMS current shouldbe used. The RMS current is given by :RMS OUT(MAX)I I 1= This formula has a maximum at V IN = 2V OUT , where I RMS = I OUT /2. This simple worst-case condition is commonly used for design because even significant deviations do not offer much relief.Choose a capacitor rated at a higher temperature than required. Several capacitors may also be paralleled to meet size or height requirements in the design. The selection of C OUT is determined by the required Effective Series Resistance (ESR) to minimize voltage ripple. Moreover, the amount of bulk capacitance is also a key for C OUT selection to ensure that the control loop is stable. Loop stability can be checked by viewing the load transient response as described in a later section. The output ripple, ∆∆V OUT , is determined by :OUT L OUT 1V I ESR 8fC ⎛⎫∆≤∆⨯+⎪⎝⎭The output ripple will be highest at the maximum input voltage since ∆I L increases with input voltage. Multiple capacitors placed in parallel may be needed to meet the ESR and RMS current handling requirement. Dry tantalum, special polymer, aluminum electrolytic and ceramic capacitors are all available in surface mount packages. Special polymer capacitors offer very low ESR value. However, it provides lower capacitance density than other types. Although Tantalum capacitors have the highest capacitance density, it is important to only use types that pass the surge test for use in switching power supplies. Aluminum electrolytic capacitors have significantly higher ESR. However, it can be used in cost-sensitive applications for ripplecurrent rating and long term reliability considerations. Ceramic capacitors have excellent low ESR characteristics but can have a high voltage coefficient and audible piezoelectric effects. The high Q of ceramic capacitors with trace inductance can also lead to significant ringing. Thermal ConsiderationsFor continuous operation, do not exceed absolute maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula : P D(MAX) = (T J(MAX) - T A ) / θJAwhere T J(MAX) is the maximum junction temperature, T A is the ambient temperature, and θJA is the junction to ambient thermal resistance.For recommended operating condition specifications, the maximum junction temperature is 125︒C. The junction to ambient thermal resistance, θJA , is layout dependent. For TSOT-23-8 (FC) package, the thermal resistance, θJA , is 70︒C/W on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at T A = 25︒C can be calculated by the following formula :P D(MAX) = (125︒C - 25︒C) / (70︒C/W) = 1.428W for TSOT-23-8 (FC) packageThe maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA . The derating curve in Figure 3 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation.RT7296CFigure 3. Derating Curve of Maximum PowerDissipationLayout ConsiderationsFor best performance of the RT7296C, the following layout guidelines must be strictly followed.Input capacitor must be placed as close to the IC as possible.SW should be connected to inductor by wide and short trace. Keep sensitive components away from this trace.Keep every trace connected to pin as wide as possible for improving thermal dissipation.SW should be connected to inductor by Wide andVia can help to reduce power trace and improve thermal dissipation.trace wider for thermal.Figure 4.
