Aperçu du produit
The NCP1351LEDGEVB is an universal Input, 20W, LED ballast evaluation board for NCP1351 current mode controller. The NCP1351 targets low power off line flyback switched mode power supplies where cost is of utmost importance. This controller provides a low cost, variable frequency, flyback converter. It incorporates a very low quiescent current allowing for high value resistors to be used as a start up circuit direct from the HV rail. The design comprises and input pi filter, bridge rectifier (using low cost 1N4007 diodes), bulk capacitors and line inductor in filter arrangement, the power stage, rectifier diode and smoothing capacitors. Feedback is CVCC, constant current drive for the LED's with a constant voltage in the event of an open circuit output.
- Wide input voltage range from 85Vac to 265Vac
- Small size and low cost
- The NCP1351LEDGEVB provides good line regulation
- High efficiency
- Overload and short circuit protection
