IR3598
Overview
The IR3598 is a high‐efficiency dual driver capable of switching a pair of high and low side N‐channel MOSFETs in synchronous buck converters and is optimized for use with IR’s Digital PWM controllers to provide a total voltage regulator solution for today’s advanced computing applications. In a space saving 16‐pin QFN package, the IR3598 can significantly improve density in high phase count voltage regulators saving over 50% board space versus conventional drivers.
- Dual MOSFET drivers in single 16 pin QFN package
- Buck Converter Driver Vin 4.0 to 13.2Vdc
- Multimode operation to configure the driver as either dual or doubler/interleaved mode drivers
- Variable Gate drive from 4V to 13V to optimize system efficiency
- 5V VCC and VDRV capability for sleep states where only 5V is available
- Large drivers designed to drive 3nF in < 12ns with any voltage from 5V to 12V (typ) supplied to the VDRV pin
- Low side driver - 0.85Ω source/0.38Ω sink
- High side driver - 1.1Ω source/0.60Ω sink
- Propagation delays < 20ns
- Integrated bootstrap diode on both drivers
