Applications

• Single and multi-output power supplies in appliances, home and

business automation, and industrial systems

Description

The LinkSwitch-XT2SR family dramatically increases the efficiency of

auxiliary power supplies used in appliances, consumer products and

industrial applications. Ideal for non-isolated designs with a high

current, 5 V output, this advanced flyback controller can achieve >90%

full load efficiency. High efficiency is maintained over to load range,

with >85% efficiency at 100 mW load. No-load consumption is <5 mW.

The default 5 V main output can be adjusted via optional external

feedback resistors.

Power for start-up and normal operation is supplied from the DRAIN

and VOUT pins, eliminating the need for a bias winding and associated

circuitry.

The SO-16 package and a low number of external components make

the LinkSwitch-XT2SR ICs ideal for compact designs.
