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 Ld 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 systems 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 ?% 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
controllers adjustable overcurrent function monitors the
output current by using the voltage drop across the upper
MOSFETs r
DS(ON)
. The linear regulator outputs are
monitored via the FB pins for undervoltage events.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-02.
