NXP SSL5021

Description

Single PCB driver and LED solution for non-dimmable candle applications based on SSL5021BTSNXP SSL5021 and SSL5031 LED Drivers are designed for non-isolated non-dimming LED solutions. SSL5021 and SSL5031 support lighting from 5W to 25W LED lamps. This makes them idea for applications ranging from candela shaped lamps to integrated fixtures, TLED and PAR lamp shapes.

Features

Driving LED strings from a rectified mains supplyOptimized for high power factor/low-THD operation (SSL5031)Small electronic Bill of Materials (BOM) enabling a compact solution and a small, single layer Printed-Circuit Board (PCB) footprintExcellent line and load regulation and LED output current accuracy (<±3%)Efficient BCM operation with:No reverse recovery losses in freewheel diodeZero Current Switching (ZCS) and valley switchingMinimal inductance value and size requiredHigh efficiency (up to 93%)Ultra low IC current during operation (<150µA)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)Thermal foldback protection via a single PTC or NTC resistor (SSL5021BTS and SSL5031BTS only)

Typical applications

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