DC-DC Converters

February 1, 2010

VPT (Blacksburg, VA) has introduced the VPT100+ 2800 Series DCDC converter modules that offer up to 100W of output power per unit and parallel operation of up to five units. They are available in single output versions of 3.3V, 5V, 7V, 12V, 15V, and 28V, as well as dual output versions of ±12V and ±15V. They feature low output noise, up to 91% efficiency, and an input voltage range of 16 to 40 volts, meeting MIL-STD-704 requirements for avionics applications. Operating temperature ranges from -55 °C to 100 °C. In a compact, quarter-brick size, the modules include six-sided metal cases for improved EMI and mechanical/environmental performance. They also feature a high-input transient voltage of 50 volts for one second, magnetic feedback, undervoltage lockout, indefinite short circuit protection, and current limit protection.
