EJW1130H 2A Peak, 44V Multi-Topology LED Driver

描述
EJW1130H是一個單片集成的電流模式控制的LED驅動器,支援模擬調光和PWM調光。採用高壓側LED電流檢測模式,EJW1130H可以配置成Buck、boost、buck-boost拓撲以滿足不同規格LED驅動的需要。內部集成的44V/2AN-MOSFET確保晶片高效率運行。輕載時,EJW1130H通過降低頻率以維持高效率。EJW1130H晶片集成SW過壓鎖定保護,有效實現LED開路保護;集成過溫保護,增強晶片的可靠性。EJW1130H提供SOT23-6和ESOP8兩種封裝,所需週邊元器件簡單,成本低。
