Abstract
A power circuit includes a PWM circuit for generating a pulse wave, a first control signal and a second control signal, a switching mode voltage stabilizer circuit, a first control circuit and a second control circuit. The PWM circuit includes a pulse wave pin, a first control pin and a second control pin. The switching mode voltage stabilizer circuit receives the pulse wave via the pulse wave output pin, and converts an external input voltage into a first direct voltage under control of the pulse wave. The first control circuit receives the first control signal via the first control pin. The second control circuit receives the second control signal via the second control pin and the first direct voltage, and converts the first direct voltage into a second direct voltage.
