Abstract :
A novel self-generated low-voltage power supply for the gate-driver of high-voltage off-line switching model power supply IC is described. The structure and properties of the device are analyzed and simulated. The experimental results have verified that the structure can realize the self-generated function, be controlled by the low-voltage logic signal and get 14 V of the low-voltage power supply. Using this novel power supply structure for the off-line switching model power supply IC can save the cell area, reduce the power consumption of the circuit, make control be easily and supply enough large output voltage for the power supply of the gate driver as well.
