Abstract:
A control system of a DC to DC converter skips switching pulses according to the output of an overvoltage protection circuit. The overvoltage protection circuit includes an overvoltage threshold voltage control section that lowers an overvoltage threshold voltage when the pulse width has a minimum valve. The control system both improves the output voltage accuracy of the DC to DC converter under a light load and promotes a quick return to normal operation after an overvoltage protection operation under a heavy load.
