General Description

The SY21314 high efficiency step-up regulator operates using current mode control over a wide input voltage range from 3V to 33V.

It integrates an N-channel MOSFET with low 120mΩ 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.
