Applicationsn Car Charger.n Battery Charger.n USB Power Supply. General DescriptionThe XL2012 is a 150 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 2.4A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator.The XL2012 built in output short protection function. When short protection function happens, the chip will be shutdown.An internal compensation block is built in to minimize external component count.Figure1.

TP4054 线性锂离子电池充电器
描述
TP4054 是一款完整的单节锂离子电池采用恒定电流/恒定电压线性充电器。其 SOT 封装与较少的外部元件数目使得 TP4054 成为便携式应用的理想选择。 TP4054 可以适合 USB 电源和适配器电源工作。由于采用了内部 PMOSFET 架构，加上防倒充电路，所以不需要外部检测电阻器和隔离二极管。热反馈可对充电电流进行调节，以便在大功率操作或高环境温度条件下对芯片温度加以限制。充电电压固定于 4.2V，而充电电流可通过一个电阻器进行外部设置。当充电电流在达到最终浮充电压之后降至设定值 1/10 时， TP4054 将自动终止充电循环。当输入电压（交流适配器或 USB 电源）被拿掉时，TP4054 自动进入一个低电流状态，将电池漏电流降至 2uA 以下。也可将 TP4054 置于停机模式，以而将供电电流降至 45uA。TP4054 的其他特点包括充电电流监控器、欠压闭锁、自动再充电和一个用于指示充电结束和输入电压接入的状态引脚。

An internal compensation block is built in to minimize external component count.Figure1. Package Type of XL401212A 300KHz 32V Buck DC to DC ConverterXL4012Pin ConfigurationsFigure2. Pin Configuration of XL4012 (Top View) Table 1 Pin DescriptionPin Number Pin Name Description1 GND Ground Pin. Care must be taken in layout. This pin should be placed outside of the Schottky Diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into XL4012.2 FB Feedback Pin (FB). Through an external resistor divider network, FB senses the output voltage and regulates it. The feedback threshold voltage is 0.8V.3 SW Power Switch Output Pin (SW). SW is the switch node that supplies power to the output.4, 5 VIN Supply V oltage Input Pin. XL4012 operates from a 5V to 32V DC voltage.
