0.25W 3KVDC Isolated Miniature Single Output DC/DC Converters 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. SELECTION GUIDE Part Number Add suffix “P” for continuous short circuit protection, for example TKA0505SAP-W25.
