Overview

The HIP6301 multi-phase PWM control IC, in conjunction with its companion gate drivers (HIP6601B, HIP6602B, HIP6603B, or HIP6604B) and external MOSFETs, provides a precision voltage regulation system for advanced microprocessors. Multi-phase power conversion offers significant advantages over earlier single-phase converter configurations by distributing power and load current, resulting in smaller, lower-cost transistors and fewer input/output capacitors.

Key Features:

• Multi-phase power conversion
• Precision channel current sharing using lossless current sampling with rDS(ON)
• Precision CORE voltage regulation with ±1% system accuracy over temperature
• Microprocessor voltage identification input: 5-bit VID input, 1.100V to 1.850V in 25mV steps
• Programmable "droop" voltage
• Fast transient recovery time
• Overcurrent protection
• Automatic selection of 2, 3, or 4-phase operation
• High ripple frequency: 100kHz to 6MHz (channel frequency x number of channels)
• Pb-Free and RoHS compliant options available
