General Description

The XL2596HVP is a 150 KHz fixed

frequency buck DC/DC converter, capable

of driving a 2A load with high voltage, high

efficiency. The XL2596HVP supports wide

input operating voltage range of 4.5V ~ 50V

and a maximum duty cycle of 100% output. A

built-in loop compensation module reduces

components in the system, lowering power

system cost and reducing printed circuit

board space. The XL2596HVP is available in

adjustable, fixed 3.3V, 5.0V and 12V

versions. The XL2596HVP has built-in

thermal shutdown, current limit protection

and output short protection function and so

on. When the output short protection

function happens, the operation frequency

will be reduced about from 150KHz to

30KHz.

Applications

 Automotive Electronics

 Industrial Control

 Networking Equipment

 Internet of Things
