Product Overview

The RDK-506 from Power Integrations is a reference design kit (DAK) which provides the essential materials to get started on next power supply design. This is a reference design for a 1.44W non-isolated buck converter using LinkSwitch -TN2 LNK3204D/P/G. The LinkSwitch-TN2 LNK3204D/P/G is a highly energy efficient off-line switcher IC with integrated system level protection for low component count power supplies. It has an input voltage of 85VAC to 265VAC and 12V, 120mA output. It is used in small appliances.
  • 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
