Abstract
A switched mode power supply includes a modulator s an input for receiving a sense signal and an output for developing a pulse modulated signal. An output switch is coupled to the modulator and is switched in accordance with the pulse modulated signal. A generator develops a supply voltage responsive to operation of the switch. A feedback circuit coupled between the modulator output and a modulator input limits the duty cycle of the pulse modulated signal.
