The RT9394 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 2.8V to VOUT. Internal soft-start circuitry effectively reduces the in-rush current both while start-up and mode change.

The RT9394 features very low quiescent current, over- current protection and short circuit protection.

The RT9394 is available in WDFN-6SL 2x2 package.
