Power Integrations LinkSwitch™-TN2 (LNK3207)

The newest member of the LinkSwitch-TN2 AC-DC converter IC family facilitates higher power white goods, industrial designs, and smart home & building automation. The uprated, high-efficiency parts reduce BOM count and offer flexible package options that simplify the design.

The new LNK3207 device increases available current from 360 to 575 mA, while delivering efficiency of over 80%. No-load consumption is less than 30 mW. Because LinkSwitch-TN2 ICs offer very high levels of integration, a simple, high-current buck converter can be realized using a minimum number of components, saving at least one diode compared with competing solutions.

Key features

• 575 mA output current
• High efficiency, greater than 80%
• Less than 30 mW no-load power consumption
