TKA Series
DESCRIPTION1W 3KVDC Isolated Miniature Dual Output DC/DC Converters
The TKA series are miniature, isolated 1W 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.
