Patent ID: 8368433

Claim:
A transistor driving module, coupled to a converting controller, to drive a high side transistor and a low side transistor connected in series, wherein the high side transistor is coupled to an input voltage and the low side transistor is grounded, the transistor driving module comprising: a high side driving unit, generating a high side driving signal to turn the high side transistor on according to a duty cycle signal of the converting controller; a low side driving unit, generating a low side driving signal to turn the low side transistor on according to the high side driving signal; a current limiting unit, coupled to the high side transistor and the high side driving unit, and generating a current limiting signal when a current flowing through the high side transistor higher than a current limiting value to stop the high side driving unit generating the high side driving signal; and an anti-short through unit, coupled to the high side driving unit and the low side driving unit to control the generations of the high side driving signal and the low side driving signal to have the timings of the high side driving signal and the low side driving signal non-overlapped.
