IR3548 Datasheet 60a Dual Integrated Powirstage

Manufacturer: International Rectifier (now Infineon)

Overview: 60A Dual Integrated PowIRstage IR3548.

General Description

The IR3548 is a dual integrated PowIRstage® is a with 2 pairs of co-packed control and synchronous MOSFETs and an optimized dual phase driver.

The package is optimized internally for PCB layout, heat transfer and package inductance.

The integrated driver is capable of operating as a Dual driver (2 PWM controlling 2 phases), a Doubler driver (1 PWM controlling 2 phases) or a Quad driver (1 PWM controlling 4 phases in two IR3548s).

Key Features

  • Integrated Dual, Doubler or Quad mode Driver.
  • 2 pairs of high and low side MOSFETs.
  • Peak efficiency up to 94% at 1.2V.
  • Variable gate drive, VDRV, from 4.25V to 12V to optimize system efficiency.
  • 5V VCC and VDRV capability for sleep states where only 5V is available.
  • Input voltage (VIN) range of 4.25V to 17V.
  • Output current capability of 30A/phase.
  • Switching frequency up to 1.5MHz.
  • Ultra-low Rg MOSFET technology min.
