HIP6303 Datasheet Microprocessor Core Voltage Regulator Multi-phase Buck Pwm Controller

Manufacturer: Renesas

Overview: 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 panion 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 demands of modern microprocessors. Multi-phase converters, by distributing the power and load current results in smaller and lower cost transistors with fewer input and output capacitors. These reductions accrue from the higher effective conversion frequency with higher frequency ripple current due to the phase interleaving process of this topology. For example, a three channel converter operating at 350kHz will have a ripple frequency of 1.05MHz. Moreover, greater converter bandwidth of this design results in faster response to load transients.

Key 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 undershoot of the CORE voltage, is easily programmed with a single resistor. Another feature of this controller IC is the PGOOD monitor circuit which is held low until the CORE voltage increases, during its S.
