HIP6601A, HIP6603A, HIP6604

Synchronous Rectified Buck MOSFET

Drivers

The HIP6601A, HIP6603A and HIP6604 are high frequency,

dual MOSFET drivers specifically designed to drive two

power N-Channel MOSFETs in a synchronous rectified buck

converter topology. These drivers combined with a HIP63xx

or an ISL65xx Multi-Phase Buck PWM controller form a

complete core-voltage regulator solution for advanced

microprocessors.

The HIP6601A drives the lower gate in a synchronous

rectifier to 12V, while the upper gate can be independently

driven over a range from 5V to 12V. The HIP6603A drives

both upper and lower gates over a range of 5V to 12V. This

drive-voltage flexibility provides the advantage of optimizing

applications involving trade-offs between switching losses

and conduction losses. The HIP6604 can be configured as

either a HIP6601A or a HIP6603A.

The output drivers in the HIP6601A, HIP6603A and HIP6604

have the capacity to efficiently switch power MOSFETs at

frequencies up to 2MHz. Each driver is capable of driving a

3000pF load with a 30ns propagation delay and 50ns

transition time. These products implement bootstrapping on

the upper gate with only an external capacitor required. This

reduces implementation complexity and allows the use of

higher performance, cost effective, N-Channel MOSFETs.

Adaptive shoot-through protection is integrated to prevent

both MOSFETs from conducting simultaneously.
