SSL5031CTS中文资料Compact high power factor/low-THD buck LED driver IC数据手册Silergy规格书

描述 Description

The SSL5031CTS is part of a new range of LED driver ICs for nonisolated, non-dimmable LED solutions. Complementing NXPs broad GreenChip SSL family of products, the new IC supports LED lighting applications ranging from 5W lamp power like Candela shape up to 25 W lamp power like integrated Fixtures/Luminaires, TLED and PAR lamp shapes.

特性 Features

·Driving LED strings from a rectified mains supply, high power factor/low-THD
·Small electronic Bill of Materials (BOM) enabling a compact solution and a small, single layer Printed-Circuit Board (PCB) footprint
·Excellent line and load regulation and LED output current accuracy (< ±3 %)
·Efficient BCM operation with:·No reverse recovery losses in freewheel diode
·Zero Current Switching (ZCS) and valley switching
·Minimal inductance value and size required
·High efficiency (up to 93 %)
·Ultra low IC current during operation (< 150 μA)

·Many auto-recovery protections:·UnderVoltage LockOut (UVLO)
·Cycle-by-cycle OverCurrent Protection (OCP)
·Internal OverTemperature Protection (OTP)
·Output Overvoltage Protection (OVP)

·Output Short Protection (OSP)

应用 Application

·Low cost non-dimmable, non-isolated retrofit LED lamps up to 25 W
·Low cost non-dimmable, non-isolated driver modules for LED lighting up to 25 W
