Patent ID: 6903535

Claim:
A system for driving a first and second n-channel power switching transistors, the system comprising: a power conversion circuit for generating a first regulated voltage from an input voltage and including a reference voltage generator for generating a reference voltage, and an up-converter that receives the input voltage and the reference voltage and generates the first regulated voltage; a charge pump circuit for generating a second regulated voltage from the first regulated voltage; a first voltage driver having an input for receiving a pulse stream and an output for driving the gate of the first power switching transistor, and operating from a supply voltage connected to the first regulated voltage such that the first voltage driver is capable of driving the gate of the first power switching transistor substantially close to the first regulated voltage; and a second voltage driver having an input for receiving a pulse stream and an output for driving the gate of the second power switching transistor, and operating from a supply voltage connected to the second regulated voltage such that the second voltage driver is capable of driving the gate of the second power switching transistor substantially close to the second regulated voltage.
