UCC2800 /1/2/3/4/5系列高速,低功耗集成電路包含所需的所有控制和驅動器組件用于離線和DC-DC固定頻率電流模式開關電源,零件數量最少。
這些器件具有與UC2842 /3/4/5系列相同的引腳配置,并且提供內部全周期軟啟動和電流檢測輸入的內部前沿消隱的附加功能。
UCC2800 /1/2/3/4/5系列提供最大占空比選擇和臨界電壓水平。較低的參考部件(如UCC2803和UCC2805)最適合電池供電系統,而UCC2802和UCC2804的較高參考電壓和較高的UVLO遲滯使其成為離線電源的理想選擇。
UCC280xQDRQ1系列的工作溫度范圍為40°C至125°C,符合AEC-Q100集成電路壓力測試資格。
