Datasheet XL4015 (XLSemi)

Datasheet 5A 180KHz 36V Buck DC to DC Converter XL4015 Features
„ Wide 8V to 36V Input Voltage Range
General Description
„ Output Adjustable from 1.25V to 32V The XL4015 is a 180 KHz fixed frequency „ Maximum Duty Cycle 100% PWM buck (step-down) DC/DC converter, „ Minimum Drop Out 0.3V capable of driving a 5A load with high „ Fixed 180KHz Switching Frequency efficiency, low ripple and excellent line and „ 5A Constant Output Current Capability load regulation. Requiring a minimum „ Internal Optimize Power MOSFET number of external components, the regulator „ High efficiency up to 96% is simple to use and include internal „ Excellent line and load regulation frequency compensation and a „ Built in thermal shutdown function fixed-frequency oscillator. „ Built in current limit function „ Built in output short protection function The PWM control circuit is able to adjust the „ Available in TO263-5L package 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
