General Description
These dual N- and P-Channel enhancement mode power field
effect transistors are produced using Fairchild Semiconductor's
advanced PowerTrench
tailored to minimize on-state resistance and yet maintain
superior switching performance.
These devices are well suited for low voltage and battery
powered applications where low in-line power loss and fast
switching are required.
Application
DC-DC Conversion
BLU and motor drive inverter
