ISL6432
PWM and Triple Linear Power Controller
for Home Gateway Applications
The ISL6432 provides the power control and protection for
four output voltages for use with high-performance
microprocessor and embedded controller based
communications chip sets. 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 can be
configured to generate DSP power, as well as upstream and
downstream voltages. 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 ISL6432 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.
