Abstract
Control circuits for a flyback switching voltage regulator that uses magnetic flux sensing are provided. These circuits include a flyback error amplifier circuit, a logic circuit, and a load compensation circuit. The flyback error amplifier circuit allows a flyback voltage pulse from a primary transformer winding to be employed for output voltage regulation. The logic circuit provides appropriate timing and control signals for the flyback error amplifier circuit. The load compensation circuit compensates for parasitic impedance contributions to the flyback voltage pulse without altering the stability of the flyback regulator.
