- Accurate PWM Duty Cycle ClampPDF, 58 Kb, File published: 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.
