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 compensation reduce external inductor and capacitor sizes, and the built-in internal soft-start circuitry minimizes inrush current at startup. The SY21222 is available in a compact SOT23-6 package. Features ● 3V to 33V Input Voltage Range ● 33V Maximum VOUT ● 2A Internal MSOFET Current Limit ● 5µA Shutdown Current (Typ.) ● 100µA Iq (Typ.
