Datasheet  
XL2009  
3A 180KHz 36V Buck DC to DC Converter With CV/CC Loop  
Features  
General Description  
„ Wide 8V to 36V Input Voltage Range  
„ Output Adjustable from 1.25V to 32V  
The XL2009 is a 180 KHz fixed frequency  
PWM buck (step-down) DC/DC converter,  
capable of driving a 2.5A 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

Maximum Duty Cycle 100%  
Minimum Drop Out 0.3V  
„ Fixed 180KHz Switching Frequency  
„ Maximum 3A Switching Current

„
Excellent line and load regulation  
fixed-frequency oscillator.  
„ With output constant current loop  
„ Built in thermal shutdown function  
„ Built in current limit function  
The PWM control circuit is able to adjust the  
duty ratio linearly from 0 to 100%. An over  
current protection function is built inside.  
When short protection function happens, the  
operation frequency will be reduced from  
180KHz to 48KHz. An internal compensation  
block is built in to minimize external  
component count.  
„ Built in output short protection function  
„ Available in SOP8L package  
Applications  
„ Car Charger  
„ Battery Charger  
„ LCD Monitor and LCD TV  
„ Portable instrument power supply  
„ Telecom / Networking Equipment
