Abstract

A drive circuit includes an internal oscillator and a pre-drive controller coupled to the internal oscillator. The pre-drive controller can have a switch control output configured to be coupled to a switch input. The pre-drive controller can receive switch control data, receive a clock signal, receive a synchronization signal, synchronize the internal oscillator based on the clock signal and the synchronization signal, and generate a pulse modulated switching signal at the switch control output based on the switch control data and the internal oscillator.
