International Rectifier IR3598

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. The IR3598 can be configured as two independent drivers in DUAL mode with individual PWM signals, or as an interleaved DOUBLER driver where one PWM signal is internally split to drive the two pairs of MOSFETs 180° out of phase. The inter‐leaving action is optimized internally to manage the tri‐state action of multiple phases during transients, low current single phase operation, and PS2 operation (see Figs.
