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. Internal soft-start circuitry effectively reduces the in-rush current. YB1313 al
