XL4001E1 – 2A 150kHz 40V Buck DC/DC Converter With Constant Current Loop – SOP8-EP Package
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. Tags, XL4001E1, XL4001, XLSEMI, DC to DC Converter
