The FDMS3664S is a dual N-Channel asymmetric MOSFET from On Semiconductor, housed in a PQFN8 Power56 package. The switch node is internally connected to simplify layout of synchronous buck converters. The control MOSFET (Q1) and SyncFET (Q2) are optimized for high efficiency.
Key electrical specifications include a maximum drain-to-source voltage of 30V. Q1 supports continuous drain current of 13A at TA=25°C (30A at TC=25°C package limited), while Q2 supports 25A at TA=25°C (60A at TC=25°C package limited). On-resistance is 8mΩ max for Q1 at Vgs=10V and 2.6mΩ max for Q2 at Vgs=10V. Gate charge is 29nC at Vgs=10V, and input capacitance is 1765pF at Vds=15V.
Thermal characteristics include an operating junction temperature range of -55°C to 150°C. Thermal resistance junction-to-case is 2.9°C/W for Q1 and 2.3°C/W for Q2. Power dissipation varies by mounting condition, with maximum values of 2.2W (Q1) and 2.5W (Q2) under certain conditions.
The device is surface mount, RoHS3 compliant, Pb-Free, and Halide Free. It is suitable for computing, communications, and general point-of-load applications, including notebook VCORE regulation.
