Dual/Doubler Interleaved MOSFET Driver IR3598
FEATURES
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
Capable of high output switching frequencies from 150kHz up to greater than 1MHz
Compatible with IR’s patented Active Tri‐Level (ATL) PWM for fastest response to transient overshoot as well as industry standard 3.3V and 5V Tri‐State signals in most modes
Non‐overlap and under voltage protection
Thermally enhanced 16 pin QFN package
Lead free RoHS compliant package
Low Quiescent power to optimize efficiency
BASIC APPLICATION
DESCRIPTION
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 ...
