General Description
    

    The XL4201 is a 150KHz fixed frequency  PWM  buck (step-down)

DC/DC converter, capable of driving a 2.5A 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.  An  internal  compensation  block  is  built  in to minimize

external  component  count.

Features

  1） Wide 8V to 40V Input Voltage Range

  2） Output Adjustable from 1.25V to 37V

  3） Minimum Drop Out 0.3V

  4） Fixed 150KHz Switching Frequency

  5） Maximum 3A Switching Current

  6） Internal Optimize Power MOSFET

  7） Excellent line and load regulation

  8） With output constant current loop

  9） Built in thermal shutdown function

10） Built in current limit function

11） Built in input over voltage protection

12） Recommend output power less than 13W

13） SOP8-EP (Exposed PAD) package

Applications

  1） Car Charger

  2） Battery Charger

  3） LCD Monitor and LCD TV

  4） Portable instrument power supply

  5） Telecom / Networking Equipment

  6） Buck constant current driver

  7） Monitor LED Backlighting

  8） General purpose LED lighting
