TPA-W25 Series
DESCRIPTION 0.25W 3KVDC Isolated Single and Dual Output DC/DC Converters
The TPA-W25 series are miniature, isolated 0.25W DC/DC converters in a SIP and DIP package.
They offer the ideal solution in many space critical applications for board level power distribution. The
internal SMD construction makes it possible to offer a product with high performance at low cost. The
series offers smaller size, improved efficiency, lower output ripple noise and 3KVDC isolation.

FEATURES
RoHS compliant Efficiency up to 80% Power density up to 0.85W/cm3
Operating temperature :-40 to 105 Single and dual output from a single input rail UL 94V-0 package material
Power sharing on output 3KVDC isolation Industry standard pinout
Input voltage: 3.3V, 5V, 12V, 15V Output voltage :3.3V,5V,9V,12V,15V,24V /±3.3V,±5V,±9V,±12V,±15V,±24V CE certification
