Abstract: Systems and methods for providing peak current mode control (PCMC) for power converters using discrete analog components. Peak current mode control functionality for latching, set, reset, clocking and slope compensation is provided via available analog components that provide improved performance, design flexibility, reliability, and radiation tolerance. Discrete analog components may include analog comparators, resistors, capacitors, diodes, etc.

Abstract: A circuit for providing dynamic output current sharing using average current mode control for active-reset and self-driven synchronous rectification with pre-bias startup and redundancy capabilities for power converters. The circuit communicates a secondary side feedback signal to a primary side via a bidirectional magnetic communicator that also provides a secondary voltage supply. Pre-bias startup is achieved by detection of the output current direction and controlling the gate signals of synchronous rectifiers. The circuit permits dynamic current sharing via a single-control signal and automatic master converter selection and promotion.

Abstract: Systems and methods are disclosed for providing over-voltage protection for power converters. An over-voltage protection loop includes an error amplifier that maintains an external reference voltage within a highly precise range that can be used to provide a highly precise output voltage from the over-voltage protection loop. The over-voltage protection loop may also include feedback impedance that delays the output of the over-voltage protection loop. The delay may prevent the over-voltage protection loop from being engaged due to voltage transients output from a main servo loop circuit that provides a nominal output voltage under normal operation, thus allowing the threshold voltage and output voltage of the over-voltage protection loop to be set close to the nominal output voltage of the main servo loop circuit.
