SSL5021BTS Overview
The SSL5021BTS is a highly integrated, high-precision, non-isolated MOSFET/bipolar buck controller. It is intended to drive LED lamps in universal mains non-dimmable lighting applications up to 25 W. The SSL5021BTS is designed for low-ripple applications.
SSL5021BTS Key Features
- Driving LED strings from a rectified mains supply, low-ripple (< ±5 %)
- Small electronic Bill of Materials (BOM) enabling a pact solution and a small
- Excellent line and load regulation and LED output current accuracy
- Minimal reverse recovery losses in freewheel diode
- Zero Current Switching (ZCS) and valley switching for switch turn-on
- Minimal inductance value and size required
- High efficiency (up to 91 %)
- Ultra low IC current during operation (< 150 A)
- Auto-recovery protections
- UnderVoltage LockOut (UVLO)
SSL5021BTS Applications
- Driving LED strings from a rectified mains supply, low-ripple (< ±5 %)
