2A 52KHz 40V Buck Li Battery Charger Datasheet XL4002 Features „ Wide 4.5V to 40V Input Voltage Range „ Output Adjustable from 1.235V to 37V „ Minimum Drop Out 1.5V „ Fixed 52KHz Switching Frequency „ 2A Constant Output Current Capability „ Internal Optimize Power Transistor „ Excellent line and load regulation „ TTL shutdown capability „ ON/OFF pin with hysteresis function „ With output constant current loop „ Built in thermal shutdown function „ Built in current limit function „ Built in output over voltage protection „ SOP8-EP (Exposed PAD) package General Description The XL4002 is a 52 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 2A 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 PWM control circuit is able to adjust the duty ratio linearly .
