General Description

The XL9004 is a 200KHz fixed frequency

PWM synchronous buck DC/DC converter,

capable of driving a 2.0A load with high

efficiency, low ripple and excellent line and

load regulation. XL9004 supports wide input

operating voltage range of 5V ~ 45V and a

maximum duty cycle of 100% output. Output

supports constant voltage loop and constant

current loop. A built-in loop compensation

module reduces components in the system,

lowering power system cost and reducing

printed circuit board space. The XL9004 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

200KHz to 30KHz.

Applications

 Automotive Electronics

 Industrial Control

 Networking Equipment

 Internet of Things
