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.
FEATURES
* Wide 4.5V~40V Input Voltage Range
* Output Adjustable from 1.235V~37V
* Minimum Drop Out 1.5V
* Fixed 150kHz Switching Frequency
* 2A Constant Output Current Capability
* Internal Optimize Power Transistor
* Excellent line and load regulation
* TTL shutdown capability
* ON/OFF pin with hysteresis function
