SY21242 Datasheet (Silergy) - 2.5A Current Limit Step-Up Regulator

SY21242, 2.5A Current Limit Step-Up Regulator

The SY21242 high efficiency step-up regulator operates using current mode control, over an input voltage range from 2V to 6V.

It integrates an Nchannel MOSFET with low 120mΩ RDS(ON) to minimize conduction loss.

The 1MHz switching frequency and internal compensation reduce external component count an
