Emerson Network Power Launches New Sixteenth-Brick DC-DC Converter Series

Emerson Network Power launched the ALD15 sixteenth-brick dc-dc converter series. Well suited for use with telecom-standard 48V power supplies, the converters are capable of achieving up to 92% efficiency at full load and are extremely cost-effective when used in applications requiring up to 35W of output power. The low profile ALD15 series has an installed height of just 0.35 inches, making it well suited for systems that require tight inter-board spacing or where sufficient separation between the converter and adjacent boards is needed.

Available in five power ratings (13A at 1.8V, 11A at 2.5V, 10A at 3.3V, 7A at 5V and 2.75A at 12V), ALD15 converters accept a wide input voltage range of 36 to 75Vdc, and feature outputs that can be adjusted from 90 to 110% of nominal voltage via external trim resistors. They are equipped with a rich set of standard features designed to deliver best-in-class performance, including differential remote sense, remote on/off facilities, undervoltage lockout and non-latching overvoltage protection. The converters are also protected against overcurrent and overtemperature conditions.

All models feature a compact 1.3 by 0.9 inch sixteenth-brick footprint, making them 43% smaller than converters using a conventional eighth-brick form factor. Available in through-hole and surface-mount configurations, ALD15 converters’ pin assignments are also identical to standard quarter- and eighth-brick converters, simplifying design and enabling an alternative compact front-end power solution for system designers.

The ALD15 converters have an estimated mean time between failures (MTBF) of more than one million hours and offer a wide ambient operating temperature range of minus 40 to plus 85°C, enabling reliable deployment in a variety of demanding environments. They are also fully RoHS compliant per EU directive 2002/95/EC, meet basic insulation requirements and are certified with international safety and performance standards, including EN60950-1 TUV and UL/cUL 60950-1.

Emerson’s ALD15 sixteenth-brick dc-dc converter series is available now and is priced at $21 per unit in production quantities.
