Abstract
An integrated circuit controller for power conversion systems that provides for the control of parallel phased semiconductor switches without the need for separate filter inductors for each switch. The controller derivates two phased clock signals from a source clock, generates ramp signals, modulates ramp signals, and outputs phased gate drive signals to control parallel phased switches.
