LTC1753 - 5-Bit Programmable Synchronous Switching Regulator Controller for Pentium® II Processor

The LTC1753 free-runs at 300kHz and can be synchronized to a faster external clock if desired. It provides a phase lead compensation scheme and under harsh loading conditions, the PWM duty cycle can be momentarily forced to 0% or 100% to reduce the output voltage recovery time.
