DER-237 - High Efficiency 18 W Power SupplyThis document is an engineering report describing an adapter power supply utilizing a TOPSwitch-JX TOP264VG. This power supply is intended as a general purpose evaluation platform for adapter application that operates from universal input and provides a 12 V, continuous 18 W output. PCB board dimension is 35 mm x 50 mm. 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.
