RDK-721

RDK-721 is a 2.75W non-Isolated buck converter using LinkSwitch-TN2 (LNK3207D) for home and building automation. This highly integrated solution was designed for a compact size (1” x 1” x 0.5”). It offers <lt/>40mW no-load input power at 230VAC and 0 to 50°C ambient temperature operation range. Optimized for low audible noise performance, the solution offers features such as 1KV differential line surge protection, load short-circuit protection and overtemperature protection with hysteretic recovery. Used as 2.75W non-isolated buck converter for home automation using LinkSwitch-TN2.

• 85VAC to 265VAC input
• Non-isolated 5V / 550mA output (±7%) for Wi-Fi and relay power
