Uprated LinkSwitch AC-DC Converter ICs From Power Integrations Increase Available Current by 60%

Uprated LinkSwitch AC-DC Converter ICs From Power Integrations Increase Available Current by 60%

High-efficiency LNK3207 ICs reduce BOM count and simplify buck converter design for appliances, sensors and metering applications

Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today 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.

Silvestro Fimiani, product marketing manager at Power Integrations said: “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.”

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. 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.

Availability & Resources

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. For further inquiries contact a Power Integrations sales representative or one of the company’s authorized worldwide distributors: Digi-Key, Farnell, and Mouser.
