HIP6017B - Advanced PWM and Dual Linear Power Control

General Description

This pin is connected to the PWM converter’s output voltage.

The PGOOD and OVP comparator circuits use this signal to report output voltage status and for over-voltage protection.

Connect UGATE pin to the PWM converter’s upper MOSFET gate.

Key Features

  • Provides 3 Regulated Voltages - Microprocessor Core, Clock and GTL Power.
  • Linear Controller Drives Either N-Channel MOSFETs or Bipolar Transistors.
  • Operates from +3.3V, +5V and +12V Inputs.
  • Simple Single-Loop PWM Control Design - Voltage-Mode Control.
  • Fast Transient Response - High-Bandwidth Error Amplifier - Full 0% to 100% Duty Ratios.
  • Excellent Output Voltage Regulation - Core PWM Output: ±1% Over Temperature - Other Outputs: ±2.5% Over Te.

HIP6017B PRELIMINARY Data Sheet March 1999 File Number 4585 Advanced PWM and Dual Linear Power Control The HIP6017B provides the power control and protection for three output voltages in high-performance microprocessor and computer applications. The IC integrates a PWM controller, a linear regulator and a linear controller as well as the monitoring and protection functions into a single 28 lead SOIC package. The PWM controller regulates the microprocessor core voltage with a synchronous-rectified buck converter. The linear controller regulates power for the GTL bus and the linear regulator provides power for the clock driver circuits. The HIP6017B includes an Intel-compatible, TTL 5-input digital-to-analog converter (DAC) that adjusts the core PWM output voltage from 2.1VDC to 3.
