Dual Linear Controller for High Current Voltage Regulation

Datasheet

Products

Overview

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, N-channel 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.
