Abstract
A boost converter with the fast discharge function includes a bridge rectifier, a boost inductor, a power switch element, an output stage circuit, a detection and control circuit, a discharge circuit, and an MCU (Microcontroller Unit). The bridge rectifier generates a rectified voltage according to a first input voltage and a second input voltage. The boost inductor receives the rectified voltage. The power switch element selectively couples the boost inductor to a ground voltage according to a clock voltage. The output stage circuit is coupled to the boost inductor, and is configured to generate an output voltage. The detection and control circuit generates a control voltage according to the rectified voltage and the output voltage. The discharge circuit is coupled to the output stage circuit. The MCU generates the clock voltage. The MCU selectively enables or disables the discharge circuit according to the control voltage.
