LD1596

DESCRIPTION

The UTC LD1596 is a 150KHz fixed frequency PWM buck

(step-down) DC/DC converter, capable of driving a 2A load with

high efficiency.

The PWM control circuit is able to adjust the duty ratio linearly

from 0~100%. An enable function, an over current protection

function is built inside. An internal compensation block is built in to

minimize external component count.
