产品概览
FDS9926A from onsemi: dual N-ch MOSFET, 30V, 6.7A, 22mOhm RDS(on) at 4.5V. Logic-level gate drive. Two independent channels for half-bridge or synchronous buck.
工作原理
Enhancement-mode N-channel. VGS greater than VGS(th) creates channel for current flow. Low RDS(on) minimizes conduction loss. Two channels for push-pull configurations.
