TKE-W75 Series
DESCRIPTION
0.75W Isolated Miniature Single Output DC/DC Converters
The TKE-W75 series are miniature, isolated 0.75W 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.
