High performance DC/DC converters with 1.5 million hours MTBF

The range of DC/DC converters from PowerGood is available from Ideal Power. The new ESBN, ESCN and ESAN series power supplies are highly reliable, with a Mean Time Between Failure (MTBF) of 1.5 million hours.

The high reliability and performance of the converters makes them well-suited to robotics and other instrumentation applications, as well as transportation and railway applications. The converters are supplied completely encased to protect against harsh environments, and meet the EN61000 safety standard.

To improve reliability, the converters have fewer components, with no life constraining capacitors. The products are available with embedded heat sink as an option which allows them to work under  extended operating temperature range of -40ºC to 115ºC (for the ESBN series) or -45ºC to 115ºC (for the ESCN series). The ESAN offers an operating temperature range of -40ºC to 70ºC.

The new devices are isolated, board-mountable fixed switching frequency DC/DC converters that use synchronous rectification to achieve high power conversion efficiency of up to 89% (ESAN and ESBN) or 90% at 5V/8A full load (ESCN).

They provide input-to-output isolation of up to 6000Vdc (ESAN), 1600Vdc (ESBN) or 2000Vdc (ESCN), with a 2:1 / 4:1 ultra-wide input range. Output power is up to 15W (ESAN), 30W (ESBN) or 60W (ESCN).

The converters are provided in a compact package with an industry-standard pinout. The ESBN measures 1.0″ x 1.0″ x 0.4″ or 0.5″ (25mm x 25mm x 10 or 12mm), while the ESCN measures 2.0″ x 1.0″ x 0.4″ (51mm x 25mm x 10mm). The ESAN is provided in a DIP24 package, measuring 1.27” x 0.65” x 0.4” (32mm x 17mm x 10mm).
