Datasheet
XL2596
General Description
The XL2596 is a 150 KHz fixed frequency
PWM buck (step-down) DC/DC converter,
capable of driving a 3A 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
and a short circuit protection function are
built inside. When OCP or SCP happens, the
operation frequency will be reduced from
150KHz to 30KHz. An internal compensation
block is built in to minimize external
component count.
