Datasheet  
XL4005  
5A 300KHz 32V Buck DC to DC Converter  
Features  
General Description  
n Wide 5V to 32V Input Voltage Range  
n Output Adjustable from 0.8V to 30V  
The XL4005 is a 300KHz fixed frequency  
PWM buck (step-down) DC/DC converter,  
capable of driving a 5A load with high  
efficiency, low ripple and excellent line and

EN pin with hysteresis function  
Built in thermal shutdown function  
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. When short protection function  
happens, the operation frequency will be  
reduced from 300KHz to 60KHz. An internal  
compensation block is built in to minimize  
external component count.
