Datasheet  
XL4001  
2A 150kHz 40V Buck DC/DC Converter With Constant Current Loop  
Features  
General Description  
„ Wide 4.5V to 40V Input Voltage Range  
„ Output Adjustable from 1.235V to 37V  
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

With output constant current loop  
Built in thermal shutdown function  
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.
