30 V N-Channel Power MOSFETs Integrate Schottky Diodes
Mon, 04/26/2010 - 6:23am
ON Semiconductor introduced new 30 V N-channel power MOSFETs with integrated Schottky diodes. The NTMFS4897NF, NTMFS4898NF and NTMFS4899NF have maximum RDS(on) values of 2 m-Ohm, 3 m-Ohm and 5 m-Ohm respectively at 10 V, optimized for synchronous side in buck converter applications to achieve higher power efficiency. Typical gate charge specifications of 39.6 nC, 25.6 nC and 12.2 nC respectively (at Vgs of 4.5 V) ensure that switching losses are also kept to a minimum. Typical applications include DC-DC conversion, point-of-load conversion and low side switching tasks for servers, telecom network infrastructure, PCs, notebook computers and games consoles. Pricing for these devices ranges from $0.45 to $0.90 per unit in 10,000 unit quantities.
