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
