MOSFET and Schottky Rectifier
The FETKY
product family incorporates low RDS(on), true logic level MOSFETs
packaged with industry leading, low forward drop, low leakage Schottky Barrier rectifiers
to offer high efficiency components in a space saving configuration. Independent pinouts
for TMOS and Schottky die allow the flexibility to use a single component for switching
and rectification functions in a wide variety of applications such as Buck Converter,
Buck–Boost, Synchronous Rectification, Low Voltage Motor Control, and Load Manage-
ment in Battery Packs, Chargers, Cell Phones and other Portable Products.
HDTMOS Power MOSFET with Low VF, Low IR Schottky Rectifier
Lower Component Placement and Inventory Costs along with
Board Space Savings
Logic Level Gate Drive — Can be Driven by Logic ICs
