2A 150kHz 40V BUCK DC/DC CONVERTER WITH LED DRIVER AND BATTERY CHARGE
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.
