MC33567 - Linear Controller with Dual High Current Voltage Regulation
Voltage regulation
The MC33567 dual linear power controller is designed to facilitate power management in motherboard applications where reliable high current supply aircraft regulation is required. It provides the interface to the two drivers, sense and control signals to external N-channel MOSFETs for two different power regulation planes. Undervoltage, short circuit detection places the operating system into protection mode pending removal of the short circuit.
Features • Two independent regulated power supplies • MC33567-1: 1.515 V - supplies GTL and AGP planes 1.818 V - supplies for I/O planes and memory termination • MC33567-2: Dual 2.525 V supplies for clock and memory • MC33567 - 3: 2.3 V - Supply voltage 1.2 V - Supply voltage • Under-voltage short circuit protection • Power supply under-voltage detection • N-channel MOSFET drive capability • 3.3 V AGP card detection bypass function • Lead-free package may be available. G - suffix indicates A lead-free lead-free package
Application • Motherboard • Dual Power Supply
