1/16 Brick DC/DC Converter For PoE Applications


RECOM has rolled out a new DC/DC converter in industry standard 1/16th brick format and pinning (33mm x 23mm). The RPA50S can provide up to 50W to power applications including industrial power supplies, telecom and PoE circuits.

The RPA50S is a low cost 50W DC/DC converter with exceptional reliability and efficiency.

The modules feature a 4:1 input range covering 24V, 28V, 48V or 57V nominal input voltages with tightly regulated output voltage options of 3.3V, 5V or 12V, all with +10%/-20% trim.

An input voltage surge capability of up to 100V makes long supply cables unproblematic and the output sense pins can be used to compensate for long output cable voltage drops, says Recom.


The enable pin draws only 1mA, allowing PoE PD interface controllers to directly drive the converter from the PG output. These advanced converters use planar transformer technology to give a low profile design with an isolation voltage of 2.25kVDC/1 minute (basic insulation grade).

The modules offer 91% efficiency permitting operation from -40°C up to +54°C full load, or up to +85°C with derating, using natural convection cooling only.

The modules incorporate full protections (SCP, OVP, OCP, OTP, UVLO).

Leveraging fully-automated manufacturing, the converters are claimed to be highly reliable and robust, even under highly stressful operating conditions. They are IEC/EN/UL60950-1 certified and come with a three-year warranty.

Samples are now available at all authorized distributors. For more information, visit www.recom-power.com
