SSL5031BTS - Compact high power factor/low-THD buck LED driver IC
Features
- This device is no longer available. Please see the EOL notice.
- 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)
- Thermal foldback protection via a single PTC or NTC resistor
Typical Application
Description
The SSL5031BTS is part of a new range of LED driver ICs for non–isolated, non-dimmable LED solutions. Complementing NXP’s broad GreenChip SSL family of products, the new IC supports LED lighting applications ranging from 5 W lamp power like Candela shape up to 25 W lamp power like integrated Fixtures/Luminaires, TLED and PAR lamp shapes.
Applications
- 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
