40.5 W, High PF (>0.95) Driver for LED Streetlight
PI is pleased to offer DER-340, a design for a non-isolated high power factor (PF) LED driver for streetlights. This new design drives a nominal LED string voltage of 54 V at 750 mA from an input voltage range of 90 VAC to 300 VAC. The LED driver utilizes the LNK419EG from the LinkSwitch™-PH family of ICs.
Features include:
Features include:
- Highly energy efficient
- >88% at 230 VAC
- >87% at 120 VAC
- <2% line and load regulation
- <5% IOUT tolerance
- Low cost, low component count and small, single-sided printed circuit board
- Frequency jitter allows smaller, lower cost EMI filter
- Integrated protection and reliability features
- Output open circuit / output short-circuit protected with auto-recovery
- Line input overvoltage shutdown extends voltage withstand during line faults
- Auto-recovering thermal shutdown with large hysteresis protects both components and printed circuit board
- IEC 61000-4-5, IEC 61000-3-2 Class C, and EN55015 B conducted EMI compliant
