Power switches cut adapter losses
Standby power losses in power adapters and chargers can be reduced using efficient new power switches and regulators.
Standby power losses in power adapters and chargers can be reduced using efficient new power switches and regulators The new Fairchild FSDM311, FSD200 and FSD210 integrated power switches, available from Abacus Polar, are the latest additions to the Fairchild Power Switch range and offer a number of new features such as elimination of the bias winding and burst mode operation to reduce standby power consumption to less than 0.1W

Range includes many different colours with both wide and focused viewing angles, sunlight viewability and night vision goggle compatibility.
Connectors allow easy field use
Polarising tabs help provide proper mating while latching features help provide a secure connection, even under mechanical stress and vibration in industrial environments.
The Fairchild FSDM311 is a highly integrated offline power switch for charger power supplies, integrating a fully avalanche rated SenseFET and PWM control IC, offering burst mode operation for low standby power.
Internal protection features to improve reliability include overvoltage, overload and thermal shutdown protection.
To reduce the overshoot current on the internal mosfet at plug-in, an internal soft-start circuit turns on the internal mosfet smoothly.
The Fairchild FSD210 combines a 700V SenseFET power switch with PWM control IC for charger and adapter applications.
Key features include reduction of EMI by frequency modulation of the basic 134kHz operating frequency and a standby power consumption of less than 0.1W.
The FSD210 shares the soft-start and internal protection features of the FSDM311.
The Fairchild FSD200 is similar to the FDS210 but additionally has an internal high-voltage regulator that eliminates the need for a transformer bias or auxiliary winding, thus reducing overall cost.
Its standby power consumption is less than 0.4W.
