    • A voltage comparator for comparing reference voltage applied to a first input node to an input voltage applied to a second input node. A first pair of transistors have output terminals coupled in series between the first input node and common node, and gate terminals connected together. A second pair of transistors, having both gate terminals of the pair connected to the gate terminals of the first pair of transistors, have output terminals coupled in series between a second input terminal, an intermediate node, and the common node. An inverter has an input coupled to the intermediate node and an output coupled to an output of the comparator. An optional feedback transistor might be used to latch the output of the comparator. Optional transistors might also be added to the first and second transistor pairs to selectively enable as the comparator and reset the latched output of the comparator.

    • A duty cycle balance module (DCBM) for use with a switch mode power converter. One possible half-bridge converter embodiment includes a transformer driven to conduct current in first and second directions by first and second signals during and second half-cycles, respectively. A current limiting mechanism adjusts the duty cycles of the first and second signals when a sensed current exceeds a predetermined limit threshold. The DCBM receives signals representative of the duty cycles which would be used if there were no modification by the current limiting mechanism and signals Dact—1 and Dact—2 representative of the duty cycles that are actually used for the first and second signals, and outputs signals Dbl—1 and Dbl—2 which modify signals Dact—1 and Dact—2 as needed to dynamically balance the duty cycles of the first and second signals and thereby reduce flux imbalance in the transformer that might otherwise arise.
