2A 150kHz 40V Buck DC/DC Converter With Constant Current Loop XL4001

General Description
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 frequency compensation and a 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.
