This technical brief identifies the recommended range of IAC for each of the devices within the UCC3854 family of PFC controllers. - Accurate PWM Duty Cycle ClampPDF, 58 Kb, Datei veröffentlicht: Jan 25, 2002
Power supply applications using current sense transformers require a duty cycle clamp on the pulse width modulator (PWM) to ensure transformer reset. Not all PWMs come with a duty cycle clamp presenting a problem for the power supply designer. This application note shows how to implement a duty cycle clamp by using a simple delay circuit.
