Typical FETKY applications

Keywords:FETKY? MOSFET? DC/DC converter? application note?

In consumer power electronics, it is not unusual to see both power MOSFETs and Schottky diodes operating side by side as main circuit elements. The reasons of placing power MOSFETs in conjunction with the Schottky diodes can be versatile, such as reverse current protection, DC/DC converter free-wheeling rectification (Asynchronous), switching efficiency improvement and so on. Working together, they could provide a more desirable system performance.

Needless to say, the integration of these two devices into one standard package could bring benefits. From circuit design point of view, it can minimize the parasitic influence, save the board space, add convenience of PCB routing, and lowers down the total system cost. The integration results in a new device category: FETKY. This short note tries to cover typical applications of the FETKY devices in brief.
