General Description
The XL7005A is a 150KHz fixed frequency
PWM buck (step-down) DC/DC converter,
capable of driving a 0.4A 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 enable
function, an over current protection function
is built inside. When output short protection
function happens, the operation frequency
will be reduced from 150KHz to 45KHz. An
internal compensation block is built in to
minimize external component count.
