SY21264A High Efficiency 6V, 4A, 1MHz Step-Up Regulator General Description The SY21264A high efficiency step-up regulator operates using current mode control, and can deliver 4A current over a wide input voltage range from 2V to 6V. It integrates an N-channel MOSFET with low 90mΩ 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 SY21264A is available in a compact DFN3mmx3mm-10 package.
