SY21222 Datasheet Step-up Regulator

Manufacturer: Silergy

Overview: SY21222 High Efficiency 1MHz, 2A Current Limit, Step-Up Regulator.

General Description

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.

The 1MHz switching frequency and internal pensation reduce external inductor and capacitor sizes, and the built-in internal soft-start circuitry minimizes inrush current at startup.
