SY21264A 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 pensation reduce external inductor and capacitor sizes, and the built-in internal soft-start circuitry minimizes inrush current at...
