Single-input dual-output dc-dc buck converter

This paper presents a single-input double-output synchronous dc-dc buck converter, for applications that demand two dc controlled output voltages. The proposed converter presents a component count reduction and it is considered as a monolithic device with both output voltages generated by the same integrated power converter. Besides the proposal of the suitable power converter, this paper presents its model, control strategy and modulation approach. Selected simulated and experimental results are presented as well.
