Today’s high-performance microprocessors present many challenges to their power source. High power consumption, low bus voltages, and fast load changes are the principal characteristics which have led to the need for a switch-mode DC-DC converter local to the microprocessor. A common requirement of these and similar processors are decreasing supply voltages as the processor clock frequency increases.
The Intersil ISL6430 pulse-width modulator (PWM) controllers are targeted specifically for DC-DC converters powering high-performance microprocessors with varying core voltage requirements. This device provides a cost-effective solutions for point-ofuse switch-mode, DC-DC converters for many applications.
This application note details the use of the ISL6430 in DC-DC converters for high-performance microprocessors with a fixed core voltage.
