General Description
The XL4101 is a 150KHz 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 over
current protection function is built inside.
An internal compensation block is built in to
minimize external component count.

Description
Supply Voltage Input Pin. XL4101 operates from a 4.5V to 40V
DC voltage. Bypass Vin to GND with a suitably large capacitor
to eliminate noise on the input.
Power Switch Output Pin (SW). Output is the switch node that
supplies power to the output.
Ground Pin.(Note: Connected the back exposed PAD to Pin3.)
Feedback Pin (FB). Through an external resistor divider
network, Feedback senses the output voltage and regulates it.
The feedback threshold voltage is 1.235V.
Output Current Sense Pin; (Iload=0.155V/Rcs)
