DESCRIPTION/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. This information allows
the microcontroller to reduce in-rush current by powering loads on the ac-line peak voltage.
A serial communications interface controls the eight low-side outputs; each output has an internal snubber circuit
to absorb the energy in the inductor at turn OFF. Alternatively, the system can use a fly-back diode to VIN to help
recirculate the energy in an inductive load at turn OFF.
