General Description
The XL1513 is a 380KHz fixed frequency
PWM buck (step-down) DC/DC converter,
capable of driving a 2A 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 short protection function
happens, the operation frequency will be
reduced from 380KHz to 80KHz. An internal
compensation block is built in to minimize
external component count.
