LED Driver for Solar Lamps - PR4403
Featured Product from PREMA Semiconductor GmbH
PR4403 drives and controls white LEDs out of one single battery charged by solar cells. Using the ON/OFF pin, the LED driver is suitable for operating solar lamps that switch on after sunset automatically. A solar cell in combination with a recharchable battery enables a on-going operation. An additional photodiode becomes dispensable.
Furthermore, the PR4403 prevents depth discharge that extends the life time especially from NiMH-batteries.
Applications:
- garden lamps with solar cells (decoration)
- lighting of house numbers
- automated lightning for street signs
