The SY21242 high efficiency step-up regulator operates using current mode control, over an input voltage range from 2V to 6V. It integrates an N-channel MOSFET with low 120mΩ RDS(ON) to minimize conduction loss.
The 1MHz switching frequency and internal compensation reduce external component count and save PCB space, and the built-in internal soft-start circuitry minimizes inrush current at startup.
The SY21242 is available in a compact SOT23-6 package.
