3A 52KHz 40V Buck DC to DC Converter XL2576
General Description
The XL2576 is a 52 KHz fixed frequency PWM buck (step-down) DC/DC converter,
capable of driving a 3A 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.
