    3A 380KHz 18V Buck DC to DC Converter            XL1530

    General Description

    The XL1530 is a 380KHz 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 i nternal  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.

    Features

  1） Wide 3.6V to 18V Input Voltage Range

  2） Output Adjustable from 0.8V to 16V

  3） Maximum Duty Cycle 100%

  4） Minimum Drop Out 0.6V

  5） Fixed 380KHz Switching Frequency

  6） 3A Constant Output Current Capability

  7） Internal Optimize Power MOSFET

  8） High efficiency

  9） Excellent line and load regulation

10） TTL shutdown capability

11） EN pin with hysteresis function

12） Built in thermal shutdown function

13） Built in current limit function

14） Built in output short protection function

15） Available in SOP8 package

    Applications
 

  1） LCD Monitor and LCD TV

  2） Digital Photo Frame

  3） Set-up Box

  4） ADSL Modem

  5） Telecom / Networking Equipment
