Description

The YB1313 charge pump is designed to drive up to 5 white LEDs with regulated constant current in back lit display application. 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.Internal soft-start circuitry effectively reduces the in-rush current. YB1313 also provides short circuit protection, over-temperature protection and over-voltage protection. In shutdown mode, the shutdown current is less than 1A. YB1313 is available in a TQFN-16 3x3 package.
