Коммутационные контроллеры NCV887300D1R2G

Повышающий ШИМ контроллер , 40В-3В питание, 1МГц, 800мА выход, SOIC-8

The NCV887300D1R2G is an adjustable output non-synchronous Boost Controller drives an external N-channel MOSFET. The device uses peak current-mode control with internal slope compensation. The IC incorporates an internal regulator that supplies charge to the gate driver. Protection features include internally-set soft-start, undervoltage lockout, cycle-by-cycle current limiting and thermal shutdown. Additional features include low quiescent current sleep mode and externally-synchronizable switching frequency.

• Peak current mode control with internal slope compensation
• Fixed frequency operation
• Input undervoltage lockout (UVLO)
• Internal soft-start
• Low quiescent current in sleep mode
• Cycle-by-cycle current limit protection
• Hiccup-mode overcurrent protection (OCP)
• Thermal shutdown (TSD)
