Patent ID: 10892686

Abstract:
A hysteretic controller coupled to a first inductor and a second inductor, the first inductor is coupled to a secondary side of a transformer, the second inductor is coupled to the secondary side of the transformer and the hysteretic controller includes: a hysteretic comparator including a first input, a second input, and an output, the first input configured to receive a sensed current from the first inductor and the second inductor, the second input configured to receive a differential voltage representing a potential difference between an output voltage of a power converter and a reference voltage; a pulse sequencer coupled to the output of the hysteretic comparator; and a dead-time generation circuit configured to provide a first on-time signal to a first switch coupled to a primary side of the transformer and a second on-time signal to a second switch coupled to the secondary side of the transformer, the first and second on-time signals based on a pulse signal received from the pulse sequencer.
