DESCRIPTION 
The WK3028***-15 Series of high frequency DC/DC converters offers high performance for low power, military/aerospace and aviation applications. WK3028***-15 parts provides up to 15 watts output power over the full temperature range of -55 to +105C with up to 84% efficiency.
The WK3028***-15 Series small size, low height, and hermetically sealed metal enclosures make them ideal for use in military, aerospace and other high reliability applications. Units are available with standard screening, and fully compliant class E/M screening.
The WK3028***-15 Series converters use a flyback converter design with a constant switching frequency of 430 kHz. They are regulated, isolated units using a pulse width modulated topology and built as high reliability thick-film hybrids. Isolation between input and output circuits is provided with a transformer in the forward power path and an optical link in the feedback control loop. Negative output regulation is maintained by tightly coupled magnetics.
The WK3028***-15 Series is compatible with Interpoint MHF+ Series.
