Overview
Applications Note:SY7104 High Efficiency 6V, 4A, 1MHz Step Up Regulator General Description SY7104 is a high efficiency, current-mode control Boost DC to DC regulator with an integrated 90mΩ RDS(ON) N-channel MOSFET.
The fixed 1MHz switching frequency and internal compensation reduce external component count and save the PCB space.
The build-in internal soft start circuitry minimizes the inrush current at start-up.
