Overview
HIP6601, HIP6603 Data Sheet January 2000 File Number 4819 Synchronous-Rectified Buck MOSFET Drivers The HIP6601 and HIP6603 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 HIP630x Multi-Phase Buck PWM controller and Intersil UltraFETs™ form a complete core-voltage regulator solution for advanced microprocessors.
The HIP6601 drives the lower gate in a synchronous-rectifier bridge to 12V, while the upper gate can be independently driven over a range from 5V to 12V.
The HIP6603 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 output drivers in the HIP6601 and HIP6603 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.
Both 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.
