| Corporate: www.cdtechno.com Product: www.cdpowerelectronics.com VKA100xS 100 Watt Single Output Half Brick DC/DC Converter 18-36V and 33 - 75V Input Range High Efficiency: 87% Typical at 5V 100S Transient Response 50100% Load Step 420 kHz Fixed-Frequency Operation Remote Sense Operation to +100C Baseplate Temperature Primary Remote On/Off, Choice of Pos/Neg Logic Adjustable Output Voltage Continuout Short-Circuit Protection Thermal Shutdown Case Ground Pin The VKA100xS 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 configurations. The VKA100xS's proprietary control circuitry responds to 50- 100% load steps in 100Seconds to within 1% nominal Vout. The patented fixed frequency architecture combined with surface mount technology results in a compact, efficient and reliable solution to DC/DC conversion requirements.

TORQUE, 8 IN/LBS 2.28 [57.91] MAX OUTPUT ADJUST VOLTAGE This feature allows the user to accurately adjust the module's output voltage set point to a specified level. This is achieved by connecting a resistor or potentiometer from the TRIM terminal to either the +Vout terminal (for increased Vout) or the -Vout terminal (for decreased Vout). The formulae below describe the trim resistor value to obtain a Vout change of %. VO is output voltage prior to adjustment (3.3V, 5V, 12V, 15V, or 24V). Radj - up = OVP NOTE Special attention should be given to the peak voltage deviation during a dynamic load step when trimming the output above the original set point to avoid tripping the overvoltage protection circuit. Should an OVP condition occur, the converter will go into a latch condition and must be externally reset before it will return to normal operation.
