Multi-phase voltage conversion device

Abstract

Disclosed is a multi-phase voltage conversion device, including multiple voltage converters, multiple current sensors and multiple current sensing signal generators. The multiple voltage converters are connected in parallel, and respectively generate an output voltage according to multiple control signals. The multiple current sensors correspond to the multiple voltage converters one by one. Each current sensor is coupled to two ends of the switching switch of the corresponding voltage converter for sensing the sensed current on the switching switch. The multiple current sensing signal generators correspond to the multiple current sensors one by one, each current sensing signal generator is coupled to the corresponding current sensor, generates mirror current by mirroring the sensed current, and generates current sensing signal according to the mirror current and the output voltage. The multi-phase voltage conversion device determines whether to activate the overcurrent protection mechanism according to the current sensing signal.
