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 compensation reduce external inductor and capacitor sizes, and the built-in internal soft-start circuitry minimizes inrush current at startup. The device offers overcurrent and thermal shutdown protections.
The SY21314 is available in a compact DFN3x3-10 package.
