Summary and Features

• Low cost, low component count solution (only 16 components)

• No optocoupler required

• Much higher output current than “reactive dropper” type power supplies

• High efficiency (>69% over full input voltage range)

• Less than 1 W input power with 0.5 W load

• Low no-load consumption (<0.2 W at 265 VAC)

• Fully protected against open-loop faults, output overload, short circuit and

thermal overload

• Low-cost input stage meets EMI and surge requirements

The products and applications illustrated herein (including circuits external to the products and transformer

construction) may be covered by one or more U.S. and foreign patents or potentially by pending U.S. and foreign

patent applications assigned to Power Integrations. A complete list of Power Integrations’ patents may be found
