Compact DC-DC converter delivers 20A output current
03 August 2010
Roband Electronics has added another product to its compact military spec DC-DC converter range.
The new RO-MIL-2213, which is supplied in 3.3V and 5V output versions, is capable of delivering a 20A output current from a package size measuring 76.3mm x 38.2mm x 10.2mm.
The high-efficiency, high power density single-rail unit comprises of an isolated, high-frequency, pulse width modulated push-pull converter. While it is specified to operate from a nominal 28V supply, this versatile power supply will accept a wide input voltage range from 12V-40V (5V output version) and 14.5V-40V (3.3Voutput version). Options include an 80V input surge capability and a variant that will operate from an input as low as 9V. External synchronisation is also available as an option.
The RO-MIL-2213 operates over the military temperature range without de-rating. It is unconditionally stable and does not require additional external components for correct operation. A remote sense facility is provided to compensate for any voltage drop at the load due to the length of the power supply leads. The converter is also equipped with a remote disable function. Short-circuit and over-voltage protection is provided as standard.
The unit is housed in a machined aluminium enclosure, with a mounting flange configuration that has been designed to optimise thermal impedance and provide adequate vibration support. A PCB-mounting version is also available.
All Roband Electronics DC-DC converters are manufactured in accordance with the company’s approved Quality Management System: BS EN ISO 9001:2000, BS EN 9100 and BS EN 9110. The RO-MIL-2213’s wide input voltage range and surge capability ensures its suitability for MIL-STD-704 applications.
