TKE-W1 Series
DESCRIPTION 0.1W 1.5KVDC and 3KVDC Isolated Miniature Single Output DC/DC Converters
The TKE-W1 series are miniature, isolated 0.1W 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.
