XL4201 DC-DC Buck IC

XL4201 DC to DC converter IC

The XL4201 is a 150KHz fixed frequency PWM buck (step-down) DC/DC Converter, capable of driving a 2.5 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 into minimize external component count. 

Features of XL4201 Step Down converter IC

  • Wide 8 Volts to 40 Volts Input Voltage Range
  • Output Adjustable from 1.25 Volts to 37 Volts
  • Minimum Drop Out 0.3V
  • Fixed 150KHz Switching Frequency
  • Maximum 3 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
  • Built in input over voltage protection
  • Recommend output power less than 13 Watts
  • SOP8-EP (Exposed PAD) package

Applications of XL4201 IC

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