| IC revision | 1.1 |
Description
This Application Note (AN) describes the characteristics and features of a 130 W SMPS LED demonstration board with dimmable constant current output in a voltage range from 76 V down to 38 V. High efficiency, high PF, low THD and a stable output current over the whole output voltage range makes it very suitable for high quality LED lighting such as street lights, high-bay lighting or office lighting. With the highly integrated ICL5102 (combo controller with Critical Conduction Mode (CrCM)/Discontinuous Conduction Mode (DCM) PFC and half bridge LLC integrated), the circuit design is considerably simplified, which results in space and Bill of Materials (BOM) cost savings. Furthermore, numerous monitoring and protection features ensure the highest reliability. Key specification measurements and waveforms are shown in this AN.
Features
- Input voltage range: 90–305 V AC
- Input voltage frequency: 47–63 Hz
- Regulated nominal output current: IOUTnom_min = 1.75 AMIN in an output voltage range from 38 V DC up to 76 V DC
- IOUTMIN = 74–76 mA (5 percent of IOUTnom_min at VDIM = 1.0 V)
- Output current ripple at VOUT = 76 V/1.75 A: IOUTRipplemax = 110 mAP_P (± 3 percent)
- Dimming using an analog 1–10 V interface
- STB less than 300 mW
- Time to light: tT2L ~ 350 ms at 90 V AC/VDim = 1.0 V
- Efficiency at nominal load: ~ 92.0 percent at 230 V AC
- PF: greater than 90 percent at 50 percent load (230 V ACin)
- Input current THD: less than 10 percent at 25 percent load (230 V ACin)
- Low-temperature start-up at -40°C TA
- OTP at 95 °C/auto-restart at 85°C
- Output OVP at VOUT = 90 V DC
- BO/Brown In (BI) detection: at 71 V ACIN/BI at 79 V ACIN
- Harmonics: according to EN 61000-3-2 Class C
- EMI: according to EN 55015
- Safety: according to EN 61347-2-13
- Board dimensions: 178 mm (L) × 52 mm (B) × 32 mm
Typical applications
- Dimmable and non-dimmable LED light applications
