TKA-W25 Series
0.25W 3KVDC Isolated Single and Dual Output DC/DC Converters
DESCRIPTION
:
The TKA-W25series 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.
