SY21222 Datasheet (Silergy) - Step-Up Regulator

SY21222, Step-Up Regulator

The SY21222 high efficiency DC-to-DC step-up regulator operates using current mode control, and can deliver 2A current over a wide input voltage range from 3V to 33V.

It integrates an N-channel MOSFET with low 200mΩ RDS(ON) to minimize conduction loss.
