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.
