Tiny Package, High Performance, Regulated Charge Pump

RT9361A/RT9361B

Update Alert Share

The RT9361A/B is a high performance charge pump DC/DC converter that produces a regulated 4.5V and 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 RT9361A/B features very low quiescent current, over current protection and short circuit protection.
The RT9361A/B is available in WDFN-6L 2x2, SOT-23-6 and TSOT-23-6 package.

Applications

  • Mobile phone, Smart Phone LED Backlight
