Overview
2A 150kHz 40V Buck DC/DC Converter With Constant Current Loop Datasheet XL4001 Features „ Wide 4.
5V to 40V Input Voltage Range „ Output Adjustable from 1.
235V to 37V „ Minimum Drop Out 1.
5V „ Fixed 150kHz 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 XL4001 is a 150KHz 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 from 0 to 100%.
An enable function, an over current protection function is built inside.
An internal compensation block is built in to minimize external component count.
Applications „ Car Charger „ Battery Charger „ LED Constant Current Driver Figure1.
