Vying for deployment on motherboards, voltage regulator modules, and graphics cards, the IR3093 three-phase, interleaved PWM controller supports several microprocessor families including AMD's Athlon, Opteron, and Athlon64, plus Intel's VR10.X processors. To reduce part counts, the device integrates MOSFET drivers. It operates from a 12V supply and includes a programmable linear regulator to power the gate drivers. Other features include a programmable oscillator with a frequency range of 100 kHz to 540 kHz, programmable soft start and hiccup over-current protection, dual under-voltage lockout circuits, and over-voltage protection. Available in a MLPQ-48 package, price is $3.10 each/10,000. For more information, contact Wayne Yoshida at INTERNATIONAL RECTIFIER, El Segundo, CA. (310) 252-7726.
