General Description
The XL7007 is a 180KHz fixed frequency
PWM buck (step-down) DC/DC converter,
capable of driving a 0.8A load with high
efficiency, low ripple and excellent line and
load regulation. Requiring a minimum
number of external components, the regulator
is simple to use and include internal
frequency compensation and a
fixed-frequency oscillator.
The PWM control circuit is able to adjust the
duty ratio linearly from 0 to 100%. An over
current protection function is built inside.
When short protection function happens, the
operation frequency will be reduced from
180KHz to 36KHz. An internal compensation
block is built in to minimize external
component count.
