MOSFETs Suit Up For Mobile Apps

Optimized for use in dc/dc converters found in mobile electronics, the OptiMOS3 M series 30V N-channel MOSFET family handles applications where only a 5V drive is available The devices are said to have a best-in-class on-resistance at 4.5V. For example, the BSC100N03MS G specifies a 10-mΩ RDS (on) and a maximum gate charge of 11 nC. The MOSFETs are available in 30 mm x 30 mm SSO8 and 3 mm x 3 mm S3O8 packages. In a SuperSO8 package, the devices can achieve an RDS (on) of 2 mΩ at 4.5V and 1.6 mΩ at 10V. The S3O8 package devices exhibit an RDS (on) as low as 4.3 mΩ at 4.5V and 3.5 mΩ at 10V. Depending on the MOSFET and package, prices range from $0.56 to $0.88 each/10,000. For more details, call Dean Henderson at INFINEON TECHNOLOGIES NORTH AMERICA CORP., Milpitas, CA. (919) 998-5304.
