  • Reduced component power converter with independent regulated outputs and method
    Patent number: 7233083
    Abstract: A DC to DC switching power converter includes a shared set of high-side switching elements which may be operated at approximately a duty cycle approaching 50%, and one or more sets of low-side switching elements which may be operated at a lower duty cycle. The sets of low-side switching elements may be turned off early in response to a control signal to regulate a particular output. Steering diodes are included to inhibit current from flowing between the various low-side stages when turned of at different times. Freewheeling diodes reduce the need for snubber circuitry. The control signals may be isolated by high-speed optical couplers.
