Power Integrations announced a new member of its acclaimed LinkSwitch™-TN2 AC-DC converter family. The new LNK3207 ICs facilitate higher-power offline buck converter designs for appliances and industrial applications by increasing the available output current from 360 mA to 575 mA, while also reducing BOM count.

The LNK3207 AC-DC converter ICs increase the available current by 60% while also delivering greater than 80% efficiency and no-load consumption of less than 30 mW. Each monolithic LinkSwitch-TN2 IC incorporates a 725 V power MOSFET, oscillator, on/off control for high 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.

The new LinkSwitch-TN2 ICs target mass-market appliances such as washers, dryers and coffee makers, which benefit from their design simplicity (more info, photo: Power Integrations).
