Preliminary Datasheet
LP3110
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.
