XL4501 Buck Converter

XL4501 DC to DC Converter SMD IC

The XL4501 is a 150KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 4.5 Ampere 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

  • Wide 8 Volt to 36 Volt Input Voltage Range
  • Output Adjustable from 1.25 Volts to 32 Volts
  • Minimum Drop Out 0.3 Volts
  • Fixed 150KHz Switching Frequency
  • Maximum 5 Ampere Switching Current
  • Internal Optimize Power MOSFET
  • Excellent line and load regulation
  • With output constant current loop
  • Built in thermal shutdown function
  • Built in current limit function
  • Available in TO263-5L package

Applications

  • Car Charger
  • Battery Charger
  • LCD Monitor and LCD TV
  • Portable instrument power supply
  • Telecom / Networking Equipment
  • Buck constant current driver
  • Monitor LED Backlighting
  • n General purpose LED lighting
