RECOM – RPA100E 100W and RPA300E 300W Eighth-Brick DC/DC Converters
RECOM offers two new cost-effective DC/DC Converters with outputs of 100W and 300W, available in a DOSA-compatible low-profile, through-hole eighth-brick format (58.4mm x 23mm).
The RPA100E-W 100W part has a wide 4:1 input range of 16-72V for nominal 24V, 28V and 48V supplies, and fully regulated 5V and 12V trimmable outputs are available. Full power is available to 50°C ambient in natural convection and to +85°C with forced air. Isolation is 1.5kVDC/1 min, basic grade.
The RPA300E 300W part has an input range of 36-75V for nominal 48V supplies and features an output trimmable over a wide range of 16-35V. Isolation of this part is 2.25kVDC/1 min, basic grade. The RPA300E has an integrated heat spreader that allows direct screw-fixing to a heatsink or cold wall. Full-load operation of this part without heatsinking is to 60°C with forced air and to 85°C with load derating.
Both product ranges have high power density with a typical efficiency of 94.8% (RPA300E) and 92% (RPA100E). High efficiency >90% is also maintained down to light loads, to suit applications with low standby loss requirements. The ranges include comprehensive protection against input under-voltage, short circuit, output over-current, over-voltage and over-temperature. Control features included are on/off control and remote sensing.
The RPA100E and RPA300E ranges are certified to UL/CAN/CSA 62368-1 safety standard for basic isolation and are compliant to EMC standard CISPR22 class B with an external filter.
The footprint of both parts is industry-standard DOSA-compatible, and the 100W part is just 11mm profile while the 300W part is 12.7mm. Pin-out is also standard and compatible with quarter-bricks allowing possible space saving in some applications without sacrificing power rating.
