DATASHEET HIP6303 Microprocessor CORE Voltage Regulator Multi-Phase Buck PWM Controller FN4767 Rev.0.00 December 1999 The HIP6303 multi-phase PWM control IC together with its companion gate drivers, the HIP6601, HIP6602 or HIP6603 and Intersil MOSFETs provides a precision voltage regulation system for advanced microprocessors.
Multiphase power conversion is a marked departure from earlier single channel converter configurations previously employed to satisfy the ever increasing current demand
HIP6303 Features
* of this controller IC include programmable VID codes from the microprocessor that range from 1.30V to 2.05V with a system accuracy of 1%. Pull up currents on these VID pins eliminates the need for external pull up resistors. In addition “droop” compensation, used to reduce the overshoot or undersho
