Abstract
A digital data detector is part of the primary side control electronics in a high voltage integrated circuit for regulating a power supply secondary side output potential; the detector output is responsive to the transitions of digital error data received from the supply secondary side via an electrically-isolated data transmission means. Only the transition edges are utilized by the detector, so that any non-linearity after each transition of the transmission means is immaterial. If the isolation device is a pulse transformer, the transformer core can be of relatively small volume, as full-pulse reproduction is unimportant and pulse saturation is tolerable. A multiplexer allows the primary side control electronics to initiate power supply operation; control is switched to the secondary side responsive to signal edges therefrom being detected by the digital data detector.
