High Performance Regulated Charge Pump

General Description

The LP3110 is a high performance charge pump

DC/DC converter that produces a regulated 5V output.

No external inductor is required for operation. The

operating voltage range is 2.6V to Vout. Internal

soft-start circuitry effectively reduces the in-rush

current both while start-up and mode change.

The LP3110 features very low quiescent current, over

current protection and short circuit protection.

The LP3110 is available in SOT-23-6 package.
