Abstract
A power supply start up booster circuit for providing an increased startup voltage for a switch mode control integrated circuit including a boost portion for combining a first input voltage that has a predetermined minimum value and a second input voltage that transitions from 0 volts to the predetermined minimum value to make a minimum threshold voltage, a control portion having an integrated circuit for using the minimum threshold voltage to temporarily provide a voltage input at the integrated circuit, and an output portion for providing a permanent voltage input at the integrated circuit and an output supply voltage to an external circuit.
