General Description

The XL9026 is a 120KHz fixed frequency

PWM synchronous buck DC/DC converter,

capable of driving a 6A load with high

efficiency, low ripple and excellent line and

load regulation. XL9026 supports wide input

operating voltage range of 5V ~ 45V and a

maximum duty cycle of 100% output. A builtin loop compensation module reduces

components in the system, lowering power

system cost and reducing printed circuit

board space.

The XL9026 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 120KHz to 30KHz.

Applications

 Automotive Electronics

 Industrial Control

 Networking Equipment

 Internet of Things
