Uprated LinkSwitch AC/DC Converter ICs Increase Available Current by 60 %

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. “These new LinkSwitch-TN2 ICs are pin-to-pin compatible with previous generations, making it simple for customers to upgrade to higher-power designs. A high-current buck converter can be created using a minimal number of easily available components while saving at least one diode over previous solutions,” said Silvestro Fimiani, product marketing manager.

The LNK3207 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. They are also suitable for sensor-based devices that require low power such as home security cameras and smart thermostats, as well as metering and IoT installations. Devices are available in three packages, PDIP-8C, SMD-8C and SO-8C, for design flexibility. The SMD-8C package is ideal for high-temperature ambient 85/105 °C applications.

LNK3207 AC-DC converter ICs are priced at $0.60 in volume product quantities. A new reference design, RDR-912 describes a 6.6 W non-isolated buck converter with 85 VAC – 265 VAC input and 12 V, 550 mA output built using the lowest possible component count.
