Reference design kit for a 1.44W non-isolated buck converter using LinkSwitch™ -TN2 LNK3204D/P/G. Typical application includes small appliance. The board provides a non-isolated 12V, 120mA 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 66KHz switching frequency of operation helps reduce EMI.
