Power supply, electronic device using the same, and output |
摘要 |
A power supply converts a first direct-current voltage into a second direct-current voltage and outputs the second direct-current voltage. The power supply includes a reference voltage generating circuit for generating a reference voltage, a control circuit for controlling an output voltage in accordance with the reference voltage, and a short-circuit detecting circuit for performing an output short-circuit protection operation, when short circuiting occurs at the output, by detecting the occurrence of short circuiting and by decreasing the reference voltage so that the output voltage is decreased.
