RT9361A/B
Tiny Package, High Performance, Regulated Charge Pump
General Description
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 V_OUT. 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.
