Abstract :
In the overcurrent-limited mode of the DC-DC converter with current-injected control, it is often observed that the excessive current flows through the main power switch when the load resistance is extremely small. The authors investigate the minimum on-time interval of the switch and analyze the current runaway phenomenon in the overcurrent-limited mode of a DC-DC converter with current-injected control. As a result, the mechanism of the current runaway phenomenon is clarified and the design condition for preventing this phenomenon is presented
