SY7304

Applications Note:SY7304 High Efficiency 33V, 4A, 1MHz Step Up Regulator General Description The SY7304 is a high efficiency, current-mode control Boost regulator. The device integrates a 120mΩ low RDS(ON) N-channel MOSFET for high efficiency. The fixed 1MHz switching frequency and internal compensation reduce external components size and count. The build-in internal soft start circuitry minimizes the inrush current at start-up. The SY7304 is available in compact DFN3×3-10 package.
