Features

* Multi-Mode Operation
* Quasi-Resonant Operation at Normal Loading
* Pulse Frequency Modulation (PFM) Operation at Light Load
* Burst Mode at No Load
* Direct Control of the Power Supply of PFC Controller for Improved Standby Power at No/Light Load
* 40KHz Minimum Frequency

Applications

* At normal load condition, it operates in QR mode with minimum drain voltage switching. To meet the CISPR-22 EMI starting at 150KHz, the maximum switching frequency is internally limited to 130KHz. It operates in PFM mode for high power conversion efficiency at light load condition. When the loading
