New 30V N-channel devices improve switching performance and overall power efficiency.

ON Semiconductor has introduced 24 new 30 volt N-channel Trench MOSFETs in DPAK, SO-8FL, µ8FL, and SOIC-8 packages featuring enhanced switching performance for synchronous buck converters in computing and game console applications.

The new series of MOSFETs utilise ON Semiconductor’s Trench technology to deliver superior on-state resistance [RDS(on)] and improved switching performance for synchronous DC-to-DC converters in PC, server, game console, VRM, and point-of-load applications. DPAK, SO-8FL, and SOIC-8 package solutions – which are a drop-in replacement for NTD48x, NTMFS48x, and NTMS48x serie s– and the new µ8FL 3.3mm x 3.3mm solution achieve industry-leading low RDS(on) in relation to packaging size.

ON Semiconductor’s new MOSFETs feature optimised low gate charge and RDS(on) to improve switching performance and overall system efficiency in an advanced packaging portfolio. All devices are lead-free (Pb-free), Halogen free, and RoHs compliant.

The NTD49x series of 32 to 79 ampere devices include the NTD4904N, NTD4905N, NTD4906N, NTD4909N, NTD4910N and NTD4913N and are offered in a 6.7mm x 10.4mm DPAK package.

The NTMFS49x series of 35 to 166A devices include the NTMFS4935N, NTMFS4936N, NTMFS4937N, NTMFS4939N, NTMFS4941N, NTMFS4943N, and NTMFS4945N. The NTMFS4933N will be launched by early 2010. They are offered in a 5mm x 6mm SO8FL package.

The NTTFS49x series of 34 to 79A devices include the NTTFS4932N, NTTFS4937N, NTTFS4939N, NTTFS4941N, NTTFS4943N, and NTTFS4945N and come in a 3.3mm x 3.3mm µ8FL package.

The NTMS49x series of 12.5 to 17A devices include the NTMS4920N, NTMS4935N, NTMS4937N and NTMS4939N. These are offered in a 5mm x 6mm SOIC8 package.

“Power management design engineers in the computing and gaming segments can improve overall efficiency by using ON Semiconductor’s newest 30 volt Trench MOSFET solutions,” said Paul Leonard, ON Semiconductor Vice president and General Manager of Power MOSFET products. “We utilised our expertise in power management and packaging technology to provide our customers with multiple solutions to meet design challenges such as improving efficiencies and saving space.”
