PFMCOT controls, widely used in high-efficiency high-speed applications, suffer from large output voltage ripple variations due to changes in the line voltage, which produce large variations in the charge pulses provided to the output capacitor. The purpose of this invention is to adapt the on-time (peak current threshold) to make the charge burst (charge pocket) independent of the input voltage.

Abstract
PFMCOT controls, widely used in high-efficiency high-speed applications, suffer from large output voltage ripple variations due to changes in the line voltage, which produce large variations in the charge pulses provided to the output capacitor. The purpose of this invention is to adapt the on-time (peak current threshold) to make the charge burst (charge pocket) independent of the input voltage.File in questo prodotto:
