HIP6521
PWM and Triple Linear Power Controller
The HIP6521 provides the power control and protection for
four output voltages in high-performance microprocessor
and computer applications. The IC integrates a voltage-
mode PWM controller and three linear controllers, as well as
monitoring and protection functions into a 16-lead SOIC
package. The PWM controller is intended to regulate the
microprocessor memory core voltage with a synchronous-
rectified buck converter. The linear controllers are intended
to regulate the computer system’s AGP 1.5V bus power, the
2.5V clock power, and the 1.8V power for the North/South
Bridge core voltage and/or cache memory circuits. Both the
switching regulator and linear voltage references provide
±
2% of static regulation over line, load, and temperature
ranges. All outputs are user-adjustable by means of an
external resistor divider. All linear controllers employ bipolar
NPNs for the pass transistors.
The HIP6521 monitors all the output voltages. The PWM
controller’s adjustable overcurrent function monitors the
output current by using the voltage drop across the upper
MOSFET’s r
DS(ON)
. The linear regulator outputs are
monitored via the FB pins for undervoltage events.
