PR4403 LED Driver for Solar LampsSupplier: PREMA Semiconductor GmbHPR4403 drives and controls white LEDs out of one single battery charged by solar cells.
0.9V- Boost Driver for White LEDs PR4401/4402Supplier: PREMA Semiconductor GmbHPR4401 andPR4402 are LED boost converters in a tinySOT23 package that drive white LEDs from a single battery cell. Output currents of 20mA (PR 4401) and40mA (PR 4402) can be achieved. The only other component needed is an inductor. A cleverly devised control circuit produces a constant output current. Maximum performance at minimum space and cost is the goal of this smart IC. The...
