General Description

The XL1507A is a 150 KHz fixed frequency

buck DC/DC converter, capable of driving a

3A load with high voltage, high efficiency.

The XL1507A 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 XL1507A is available in both adjustable

and fixed 5.0V versions. The XL1507A 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
