Synchronous Rectified Buck  
MOSFET Drivers  
Features  
• Drives Two N-Channel MOSFETs  
• Adaptive Shoot-Through Protection  
• Internal Bootstrap Device  
The HIP6601B, HIP6603B and HIP6604B 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 the ISL65xx series of Multi-Phase Buck  
PWM controllers and MOSFETs form a complete core-  
voltage regulator solution for advanced microprocessors.  
• Supports High Switching Frequency  
- Fast Output Rise Time  
- Propagation Delay 30ns  
• Small 8 LD SOIC and EPSOIC and 16 LD QFN Packages  
• Dual Gate-Drive Voltages for Optimal Efficiency  
• Three-State Input for Output Stage Shutdown  
• Supply Undervoltage Protection  
The HIP6601B 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 HIP6603B 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 HIP6604B can be configured as  
either a HIP6601B or a HIP6603B.  
• QFN Package  
- Compliant to JEDEC PUB95 MO-220 QFN—Quad Flat  
No Leads—Product Outline.  
- Near Chip-Scale Package Footprint; Improves PCB  
Efficiency and Thinner in Profile.  
The output drivers in the HIP6601B, HIP6603B and  
HIP6604B 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.  
Applications  
• Core Voltage Supplies for Intel Pentium® III, AMD®  
Athlon™ Microprocessors  
• High Frequency Low Profile DC-DC Converters  
• High Current Low Voltage DC-DC Converters

Processing Moisture Sensitive Surface Mount Devices

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
