Abstract
Hysteretic control for power converters. In an example arrangement, an apparatus includes a converter for converting an input voltage to an output voltage including a transformer; at least one primary side driver switch coupled to supply current from an input voltage terminal to the primary side of the transformer; at least one inductor coupled between the secondary side of the transformer and the output voltage terminal; at least one secondary side switch coupled between the inductor and a ground potential; and a hysteretic controller coupled to supply a first on-time signal to the at least one primary side switch and a second on-time signal to the at least one secondary side switch, the hysteretic controller configured for sensing the output voltage and having at least one current input coupled for sensing current flowing in the inductor and generating primary side driver switch on-time pulses to control the output voltage.
