Abstract
A switching controller circuit for a power converter includes analog and digital control circuits, a clock enable circuit, and a digital pulse width modulation (PWM) circuit. When the power converter is in a standby mode, the switching controller circuit operates in an analog control mode by activating the analog control circuit. When the power converter is not in standby mode, the switching controller circuit activates the digital control circuit and operates in a digital control mode. The switching controller circuit uses inexpensive electronic components and consumes less power in the analog control mode, thereby reducing standby mode power consumption.
