The UCC2863x targets high-power, primary-side regulated flyback converters. The ability to operate in both CCM and DCM make the device suitable for applications with a wide power range. The peak power mode allows transient peak power delivery up to 200% of nominal rating, with only a 25% peak current increase, maximizing transformer utilization.

The transformer bias winding is used to sense output voltage for regulation, and for low-loss input voltage sensing. Advanced sampling techniques allow CCM operation, and deliver excellent output voltage regulation performance for opto-coupler-less designs at power levels of 100 W and above.

A high-voltage current source enables fast and efficient start-up. Advanced light-load modes are deployed to reduce both controller and system power consumption at no load and light load. These modes enable potential system designs to meet 30-mW no-load power for power designs up to 30 W nominal, 60 W peak.

The device has been designed for ease-of-use and incorporates many features to enable a wide range of designs. Extensive protection features are included to simplify system design.

PMP10804 — 具有 120V AC 輸入和 24V/4A 額定輸出的初級側穩壓返馳參考設計

此參考設計在返馳電源供應器中實作 UCC28630 PSR 控制器。UCC28630 能夠在連續和不連續傳導模式下運作，從而在縮減電感器尺寸和成本的同時，實現高效率。EN60950 等安全標準要求橋式整流器 AC 側 EMC 濾波器中的任何 X 電容器在 AC 斷開時，快速放電至安全位準。  一般而言，此需求是透過與 X 電容器並聯的電阻放電元件得到滿足。然而，此電阻會造成持續功耗，進而影響待機電源性能。為了減少待機功耗並消除與傳統放電電阻器相關的固有耗損，UCC28630 裝置整合了主動 X 電容器放電電路。在此設計中，可實現低於 100mW、無負載功耗及轉換器效率超過 88%。
