XL2010中文资料3.5A 180KHz 36V Buck DC to DC Converter With CV/CC Loop数据手册XLsemi规格书

描述 Description

The XL2010 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter,capable of driving a 3.5A 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 frequency compensation and a fixed-frequency oscillator.

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.
