Power Integrations - LNK3202/3204-6 Switch

The LinkSwitch™-TN2 family of ICs for non-isolated off-line
power supplies provide dramatically improved performance compared to
traditional linear or cap-dropper solutions. Designs using the highly
integrated LinkSwitch-TN2 ICs are more flexible and feature increased
efficiency, comprehensive system level protection and higher reliability. The
device family supports buck, buck-boost and flyback converter topologies. Each
device incorporates a 725 V power MOSFET, oscillator, On/Off control for
highest efficiency at light load, a high-voltage switched current source for
self-biasing, frequency jittering, fast (cycle-by-cycle) current limit,
hysteretic thermal shutdown, and output and input overvoltage protection circuitry
onto a monolithic IC.
