Abstract:
A power supply integrated circuit includes a DC-DC boost regulating unit and a DC-AC output controlling unit. The DC-DC boost regulating unit is used for increasing a low DC voltage into a high DC voltage. The DC-AC output controlling unit is connected with the DC-DC boost regulating unit for converting the high DC voltage into a high AC voltage. A first portion of an integrated circuit chip and a plurality of passive components are collaboratively defined as the DC-DC boost regulating unit. A second portion of the integrated circuit chip is defined as the DC-AC output controlling unit.
