SY21314 - 4A Current Limit Step-Up Regulator
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
