The device can provide up to 25 mA per LED for a total of more than 125 mA. The input voltage ranges from 2.7V to 5.5V and is ideal for applications powered by a single LI-Ion or 3 to 4 NiCd, NiMH or Alkaline batteries. The 1MHz fix-frequency switching allows for tiny external components, and the regulation scheme is optimized to ensure low EMI and low input ripple.
