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
