Description: CCM PFC controller

Features

* Peak current mode CCM-operated
* 800 V high voltage startup with integrated input voltage sensing
* Active input filter capacitor discharge
* Proprietary multiplier “emulator” with minimum THD of line current in all operating conditions (CCM and DCM)
* Extre

Applications

* in a power range that spans from few hundred W to some kW. The device, thanks to a proprietary off-time modulator, operates in quasi-fixed frequency in all operating conditions. Two options are available, 65 kHz for A and 130 kHz for B. The 800 V high voltage start-up block includes also the circui
