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
