RDK-506: 1.44W, 12V @ 120mA, 85 ~ 265VAC

Summary

The evaluation board shows a buck converter circuit using Power Integration's LNK3204D/P/G. The circuit provides a non-isolated 12 V, 120 mA continuous output. In metering applications this is used to supply the control circuits and micro controller. LinkSwitch-TN2 integrates a 725V MOSFET and control circuitry into a single low cost IC. Regulation is achieved using a low cost resistor divider feedback network. The switching frequency jitter feature of the LinkSwitch-TN2 family and the 66 kHz switching frequency of operation helps reduce EMI.

Design Accelerator Kits (DAK) provide all of the essential materials to get you started on your next switch mode power supply design. The kits include a fully assembled and tested prototype power supply board, comprehensive engineering report, product samples, unpopulated circuit board, data sheet and other related documentation.
