Abstract
A converter has a boost portion and a buck portion. The boost portion supplies a boosted voltage and includes a first inductor having a first end coupled to the input terminal, a first switch coupled to a second end of the first inductor to charge the first inductor when the first switch is in its on-state, and a first capacitor for being charged to the boosted voltage. The buck portion supplies an output voltage to a load that is less than the boosted voltage and includes a second inductor in series with the load, and a second switch in series with the second inductor and the load to charge the second inductor during an on-state of the second switch. A single controller IC receives feedback signals and controls the switches to have the same duty cycle to achieve a regulated load current or voltage with low EMI.
