The XL2011 is a 150 KHz fixed frequency
PWM buck (step-down) DC/DC converter,
capable of driving a 2.1A 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
The XL2011 built in output short protection
function. When short protection function
happens, the chip will be shutdown. An
internal compensation block is built in to
minimize external component count.
USB Power Supply.
