100W and 300W DC/DC converters are DOSA-compatible

 Two DC/DC converters in an eighth brick format have been added to the Recom range. The cost-effective DC/DC products are supplied in a DOSA-compatible low-profile, through-hole form factor, measuring 58.4 x 23mm.

The RPA100E-W is the 100W output model. It has a wide 4:1 input range of 16 to 72V for nominal 24, 28 and 48V supplies. Fully regulated 5.0 and 12 trimmable outputs are available. Full power is available up to 50°C ambient in natural convection and up to +85°C with forced air. Isolation is 1.5kV DC/1 min, basic grade.

The RPA300E is a 300W model, which has an input range of 36 to 75V for nominal 48V supplies. The output is trimmable over a wide range of 16 to 35V. Isolation of this part is 2.25kV DC/1 min, basic grade. The construction includes an integrated heat spreader that allows direct screw-fixing to a heatsink or cold wall. Full load operation without heatsinking is up to 60°C with forced air and up to 85°C with load derating.

Both models have high power density with a typical efficiency of 94.8% for the RPA300E and 92% for the RPA100E. High efficiency of 90% and above is maintained down to light loads, to suit applications with low standby loss requirements. The DC/DC converters include  input under-voltage, short circuit, output over-current, over-voltage and over-temperature protection, together with on/off and remote sensing control features.

The RPA100E and RPA300E ranges are certified to UL, CAN and CSA 62368-1 safety standard for basic isolation. They are also compliant to EMC standard CISPR22 class B with an external filter.

The 100W part is just 11mm profile and 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.
