General Description
The XL9711 is a 120KHz fixed frequency
PWM synchronous buck DC/DC converter,
capable of driving a 0.6A load with high
voltage, high efficiency, low ripple and
excellent line and load regulation. XL9711
supports wide input operating voltage range
of 5V~72V and a maximum duty cycle of 90%
output. A built-in loop compensation module
reduces components in the system, lowering
power system cost and reducing printed
circuit board space.
The XL9711 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
