The ISL6432 provides the power control and protection for four output voltages for use with high-performance microprocessor and embedded controller based munications 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 synchronousrectified 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.
