Dual/Doubler Interleaved MOSFET Driver

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 significantly improve density in high

phase count voltage regulators saving over 50% board space

versus conventional drivers.

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. 8 and 9.) The DOUBLER mode can double

the effective maximum phase count from the controller, enabling

a well-controlled, high phase count voltage regulator.

The IR3598 has a proprietary circuit which maintains the MOSFET

drive strength throughout the 4.0V to 13.2V drive voltage range

thus insuring fast switching even with 5V standby drive operation

during system sleep modes. The integrated boot diodes reduce

external component count. The IR3598 also features an adaptive

non-overlap control for shoot-through protection.

The IR3598 PWM inputs are compatible with IR’s fast Active

Tri-Level (ATL) PWM signals as well as 3.3V and 5V Tri-State

PWM signals.
