A Dual-Edge Pulsewidth Modulator for Fast Dynamic Response DC-DC Converters

Maher Kayal, Adil Koukab, Giacomo Ripamonti, Stefano Michelis, Federico Faccio

Voltage regulator modules are dc-dc converters that power modern microprocessors. They must exhibit a fast dynamic response, in order to achieve satisfactory regulation performance in spite of the rapid load current variations. The pulsewidth modulator is ...
