SY21264A Datasheet (Silergy) - 1MHz Step-Up Regulator

SY21264A, 1MHz Step-Up Regulator

The SY21264A high efficiency step-up regulator operates using current mode control, and can deliver 4A current over a wide input voltage range from 2V to 6V.

It integrates an N-channel MOSFET with low 90mΩ RDS(ON) to minimize conduction loss.
