POWER CONVERSION CIRCUIT HAVING SHORT-CIRCUIT DETECTION FUNCTION AND SHORT-CIRCUIT DETECTION METHOD THEREOF

A power conversion circuit includes a first and a second power converters for generating a first and a second driving voltages respectively. The second power converter is a switching converter. In a short-circuit detection mode, the first driving voltage is regulated to the first driving level, and...

description A power conversion circuit includes a first and a second power converters for generating a first and a second driving voltages respectively. The second power converter is a switching converter. In a short-circuit detection mode, the first driving voltage is regulated to the first driving level, and the second power converter is configured to operate in a pulse frequency modulation mode to regulate the second driving voltage to a short-circuit detection level, and when a switching frequency of the second power converter exceeds a threshold frequency, a short-circuit condition between the second driving voltage and the first driving voltage is determined.
