TPIC9201 Overview
/ORDERING INFORMATION The power supply provides regulated 5-V output to power the system microcontroller and drive eight low-side switches. The ac zero-detect circuitry is monitoring the crossover voltage of the mains ac supply. The resultant signal is a low-frequency clock output on the ZVS terminal, based on the ac-line cycle.
