HIP6602中文资料Dual Channel Synchronous-Rectified Buck MOSFET Driver数据手册Renesas规格书

描述 Description

The HIP6602 is a high frequency, two power channel MOSFET driver specifically designed to drive four power N-Channel MOSFETs in a synchronous-rectified buck converter topology. These drivers combined with a HIP63xx series of Multi-Phase Buck PWM controller and Intersil’s UltraFETs® form a complete core voltage regulator solution for advanced microprocessors.
The HIP6602 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 HIP6602 have the capacity to efficiently switch power MOSFETs at high frequencies. Each driver is capable of driving a 3000pF load with a 30ns propagation delay and 50ns transition time. This device implements bootstrapping on the upper gates with only a single external capacitor required for each power channel. 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.
