RDK-506

RDK-506 is a reference design kit for a 1.44W non-isolated buck converter using LinkSwitch™ -TN2 LNK3204D/P/G. 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.

• Input: 85VAC to 265VAC, output: 12V, 120mA
• Highly integrated solution
• Lowest possible component count
• No optocoupler or Zener diode required for regulation
• Thermal overload protection with automatic recovery
• Less than 30mW no-load consumption, greater than 75% efficiency at full load
• Less than ±3% load regulation
• Suitable for small appliance

Avisos

Market demand for this product has caused an extension in leadtimes. Delivery dates may fluctuate. Product exempt from discounts.

Notas

All testing should be performed using an isolation transformer to provide the AC input to the prototype board.
