Overview
| Topology | Flyback Converter |
| Input voltage | 90-305 V |
| Output 1 | 240 V / 1 A |
| IC revision | 1 |
Description
This design used ON’s PFC controller NCL2801CDA and BUCK controller NCL30076, with a high PF and low THD performance. The NCL30076 is DC-DC buck controller for wide analog dimming range down to 1%. ON Semiconductor’s proprietary LED current calculation technique driven by zero input offset amplifiers performs precise constant current in the whole analog dimming range. PWM dimming is also provided to keep the constant LED color temperature.There is also a Auxiliary power supply board using ON’s NCP10671,which can be used to supply the Vcc power for NCL30076, NCL2801 and the Dimming circuit.
Features
- Wide analog dimming range: 1-100%
- Precise CC regulation: ±2% at 100% load
- QR operation at full load
- Low STBY current
- Protections:
- Short LED protection
- Over current protection
- Thermal shutdown
- High PF and low THD
Typical applications
- Flat TV
- Lighting Ballasts (LED, Fluorescent)
- PC Power Supplies
- All Off Line Appliances Requiring Power Factor Correction Several product configurations coded with three letters (L1,L2, L3) marked on the package will be available.
