MC33567
Dual Linear Controller
for High Current
Voltage Regulation
The MC33567 Dual Linear Power Supply Controller is designed to
facilitate power management for motherboard applications where
reliable regulation of high current supply planes is required. It
provides the Drive, Sense and Control signals to interface two
external, Nchannel MOSFETs for regulating two different supply
planes. Undervoltage short circuit detection places the operation of the
system into a protected mode pending removal of the short.
Features
" Two Independent Regulated Supplies
" MC335671: 1.515 V Supply for GTL and AGP Planes
1.818 V Supply for I/O Plane and Memory
Termination
" MC335672: Dual 2.525 V Supplies for Clock and Memory
" MC335673: 2.3 V Voltage Supply
1.2 V Voltage Supply
" Undervoltage Short Circuit Protection
" Supply Undervoltage Detection
" Drive Capability for NChannel MOSFETs
" Bypass Function for 3.3 V AGP Card Detection
" PbFree Package May be Available. The GSuffix Denotes a
PbFree Lead Finish
Applications
" Motherboards
" Dual Power Supplies
