DESCRIPTION
The PWR12XX 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
converters offer better performance and lower cost in
industry-standard packages and pinouts. The PWR12XX
Series is internally filtered. No external parts are necessary.
Surface mounted components and a low thermal resistance
encapsulant allow for superior reliability, excellent thermal
dissipation, and an extended temperature range of –25°C
to +85°C at no extra cost.

The PWR12XX Series is ideal for use on high-density PC
boards where isolated, unregulated, power is needed.
Standoffs allow for PC board cleaning, helping preserve
isolation. They also allow for visual inspection of solder
joints.

MATERIAL: Units are encapsulated in a low thermal resistance
molding compound which has excellent chemical resistance, wide
operating temperature range, and good electrical properties 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.

APPLICATION NOTES
UNBALANCED LOADS
Unbalanced loads may be used on dual output models
with either side providing up to its rated current. Output
voltages, by design, will track each other in an unbal-
anced state within ±10% of one another.
OUTPUT NOISE
Output noise can be reduced to 30mVp-p, typically, by
adding a 10µF tantalum capacitor with an equivalent
series resistance (ESR) of less than 150mΩ at 10kHz
across each output.
