ISL6440A Product details

Description

VCC (Pin 28) Provide a 12V bias supply for the IC to this pin.This pin also provides the gate bias charge for all the MOSFETs controlled by the IC.The voltage at this pin is monitored for power-on reset (POR) purposes.internal circuitry insures the core output voltage does not go negative during this process.When re-enabled, the IC undergoes a new soft-start cycle.Left open, this pin is pulled low by an internal pull-down resistor, enabling operation.FIX (Pin 2) Grounding this pin bypass

Features

Provides four regulated voltages - Microprocessor core, AGP bus, memory, and GTL bus power.
Drives N-Channel MOSFETs.
Linear regulator drives compatible with both MOSFET and bipolar series pass transistors.
Fixed or externally resistor-adjustable linear outputs.
Simple single-loop control design - Voltage-mode PWM control.
Fast PWM converter transient response - High-bandwidth error amplifier - Full 0.
100% duty ratio.
Excell.
