Product Advantage:

+It offers a wide output voltage trim range to meet a broad range of application needs and have no minimum load requirement. With the fixed-frequency switching, it can help minimize external EMI filtering requirements.

+Based on a high power density open-frame design that incorporates a thermal baseplate, it has an industry standard half-brick footprint and pin-out. Featuring a thermally optimized layout that is suitable for either conduction or forced air cooling, they offer ultra high conversion efficiencies of up to 88% at half load.

+Standard features include input undervoltage lockout, remote On/Off and differential remote sense, as well as comprehensive protection against overtemperature and output overcurrent or overvoltage conditions. The converter provides high efficiency and good performance with flexible configuration options, which is ideal for power amplifier applications, wireless networks, and telecom applications. 

+The baseplate provides a means for conduction cooling in demanding thermal environment conditions. A single-board, highly optimized thermal design contributes to superior thermal performance. If you have any questions about our products, please feel free to contact us, we will be the first time to reply.
