Product Summary

The AO4714 is a dual N-channel enhancement mode field effect transistor with schottky diode. The AO4914 uses advanced trench technology to provide excellent R DS(ON) and low gate charge. The two MOSFETs make a compact and efficient switch and synchronous rectifier combination for use in DC-DC converters. The AO4914 is co-packaged in parallel with the synchronous MOSFET to boost efficiency further AO4914 is Pb-free.
