POWER SUPPLY, POWER MANAGEMENT DEVICE APPLIED TO A POWER SUPPLY, AND METHOD FOR PERFORMING BROWN-OUT PROTECTION AND OVERHEAT PROTECTION OF A POWER MANAGEMENT DEVICE |
摘要 |
A power supply can provide brown-out protection and overheat protection. The power supply includes a rectifier, a transformer, and a power management device. The rectifier is used for receiving an alternating current voltage. The alternating current voltage has a voltage cycle. The transformer coupled to the rectifier has an inductor coupled to a switch for supplying an output voltage. The power management device is used for controlling the switch to make the inductor save power or release power. The power management device has a multi-functional pin coupled to the rectifier for receiving a detection voltage corresponding to a positive half cycle of the alternating current voltage. The multi-functional pin is also coupled to a thermistor for receiving an overheat protection signal.
