Abstract
A circuit that can avoid drops in power supply and heat generation and save on manufacturing costs with no need of external controls are configured such that: a switching transformer has a terminal that produces an output of 22V at power-on and an output of 8V during standby and a terminal that produces an output of 10V at power-on and an output of 3V during standby; the output of 22V or 8V is lowered to 5V by a regulator IC1 and applied (input) to a regulator IC2; an input of 10V or 3V is produced at the regulator IC2; at power-on, the regulator IC2 lowers 10V to 3.3V and supplies the lowered 3.3V to the inverter circuit 10f; and during standby, a regulator IC lowers 8V to 3.3V and supplies the lowered 3.3V to the inverter circuit 10f.
