RDK-242: 30W, 12V @ 2.5A, 85 ~ 264VAC

Summary

This engineering report describes a power supply employing the Power Integrations® TOPSwitch®-JX TOP266VG. This power supply operates over a universal input range and provides a 12 V, 30 W output. It has been designed and tested to operate open frame with an ambient temperature environment of up to 40 °C.

The TOPSwitch-JX, by design, maintains virtually constant efficiency across a very wide load range without using special operating modes to meet specific load thresholds. This optimizes performance for existing and emerging energy-efficiency regulations. Maintaining constant efficiency ensures design optimization for future energy-efficiency regulation changes without the need for redesign.
