5V/3.2A 150KHz 40V Buck DC to DC Converter For USB

Interface                                                                  XL2013

General Description

    The XL2013 is a 150KHz fixed frequency PWM buck (step-down)

DC/DC converter, capable of driving a 3.2A 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 XL2013 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.

Features

  1) Wide 8V to 40V input voltage range.
  2) Fixed 5V output voltage.
  3) Maximum 3.2A output current.
  4) Fixed 150KHz switching frequency.
  5) Internal optimize power MOSFET.
  6) High efficiency up to 92%.
  7) Built in output short shutdown function.
  8) Excellent line and load regulation.
  9) Built in thermal shutdown function.
10) Built in current limit function.
11) Available in TO252-5L package.

Applications

  1) Car Charger
  2) Battery Charger
  3) USB Power Supply
