Power density and light-load efficiency improvement are key issues for server, telecom and AC-DC power designers. Additionally, the synchronous rectification in these switch-mode power supplies (SMPS) designs require cost-effective power supply solutions that minimize board space while increasing efficiency and reducing power dissipation. Fairchild Semiconductor (NYSE: FCS) helps designers meet these power design challenges with the expansion of the PowerTrench® MOSFET family.
Part of the mid-voltage power MOSFET portfolio, these devices are optimized power switches that combine a small gate charge (Q G), a small reverse recovery charge (Q rr) and a soft-reverse recovery body diode, allowing for fast switching speeds. Available in a 40V, 60V and 80V rating, these devices require less power dissipation in the snubber circuitry due to an optimized soft-body diode that reduces voltage spikes by up to 15 percent over the competitor’s solution.
Employing a shielded-gate silicon technology that provides charge balance, the devices achieve higher power density, low ringing and better light-load efficiency. By using this technology, the devices achieve a lower figure of merit (Q G x R DS(ON)) while reducing driving loss to increase power efficiency.
