  • QUICK-START DC-DC CONVERTER CIRCUIT AND METHOD
    Publication number: 20030234635
    Abstract: A quick-starting low-voltage DC power supply circuit has a switch mode DC to DC converter connected to a DC supply source. A low-dropout-regulator (LDO) connected in parallel with the switch-mode DC to DC converter, and a diode is connected in series with the output of the low-dropout-regulator connecting the output of the low-dropout-regulator to the output of the switch-mode DC to DC converter. The arrangement is such that the start-up output voltage of the circuit is the output voltage of the low-dropout-regulator and the long-term output voltage of the circuit is supplied by the switch-mode DC to DC converter output.
