XRP7665 Datasheet 3a 18v Synchronous Step-down Converter

Manufacturer: Exar (now MaxLinear)

Overview: XRP7665 3A 18V Synchronous Step-Down Converter March 2013 GENERAL.

General Description

The XRP7665 is a synchronous current-mode PWM step down (buck) regulator capable of a constant output current up to 3 Amps.

A wide 4.50V to 18V input voltage range allows for single supply operations from industry standard 5V and 12V power rails.

With a 340kHz constant operating frequency and integrated high and low side 100mΩ/90mΩ MOSFETs, the XRP7665 reduces the overall ponent count and solution footprint.

Key Features

  • Pin/Function Compatible to MP1484.
  • 3A Continuous Output Current.
  • 4.50V to 18V Wide Input Voltage.
  • PWM Current Mode Control  340kHz Constant Operations  Up to 93% Efficiency.
  • Adjustable Output Voltage  0.925V to 16V Range  2.0% Accuracy.
  • Programmable Soft-Start and Enable Function.
  • Built-in Thermal, Over Current, UVLO and Output Over Voltage Protections.
  • RoHS Compliant “Green”/Halogen Free 8-Pin Exposed Pad SOIC Package.
