IR3548
Overview
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.
- 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 minimizes switching losses for optimized high frequency performance
- Synchronous MOSFET with monolithic integrated Schottky diode reduces dead-time and diode reverse recovery losses
