1 / 4 page 50 Watt Single Output Half Brick DC/DC Converter VKA50xS 18-36 V & 33 - 75V Input Range High Efficiency: 87% Typical at 5V 100 µS Transient Response 50- 100% Load Step 420 kHz Fixed-Frequency Operation Remote Sense Operation to +100 °C Baseplate Temperature Primary Remote On/Off, Choice of Pos/Neg Logic Adjustable Output Voltage Continuout Short-Circuit Protection Thermal Shutdown Case Ground Pin Corporate: www.cdtechno.com Product: www.cdpowerelectronics.com The VKA50xS Series DC/DC converters present an economical and practical solution for distributed power system architectures which require high power density and efficiency while maintaining system modularity and upgradeability. With the ability to operate over a wide input voltage range of 18 to 36 and 33 to 75 volts, these modules are ideal for use in battery backup applications common in todays' telecommunication and electronic data processing applications. The output is fully isolated from the input, allowing for a variety of polarity and grounding configura- tions. The VKA50xS's proprietary control circuitry responds to 50-100% load steps in 100 µSeconds to within 1% nominal Vout. The patented fixed frequency architecture combined with surface mount technology results in a com- pact, efficient and reliable solution to DC/DC conversion requirements.
