DESCRIPTION

The PWR11XX Series offers a broad line of low-cost, high-

performance, unregulated, single and dual output DC/DC

converters in a 24-pin DIP package. These miniature convert-

ers offer better performance and lower cost in industry-

standard packages and pin-outs. The PWR11XX Series is

internally filtered. No external parts are necessary.

Surface mounted components and a special encapsulant al-

low for superior reliability, excellent thermal dissipation, and

an extended temperature range of –25°C to +85°C at no extra

cost.

The PWR11XX Series is ideal for use on high-density PC

boards where isolated, unregulated, power is needed. Stand-

offs allow for PC board cleaning, helping preserve isolation.

They also allow for visual inspection of solder joints.

MATERIAL: Units are encapsulated in Iso-

ThermoFlex, a low thermal resistance molding com-

pound which has excellent chemical resistance, wide

operating temperature range, and good electrical proper-

ties under high humidity environments. The encapsulant

and outer shell of the unit have UL94V-0 ratings. Lead

material is brass with a solder plated surface to allow ease

of solderability.
