Miniature DC/DC converters comply to standards for industrial applications

The PUA-A, PUC-B and PUB-M are isolating converters providing output power of up to 1W, with no minimum load required.

Efficiency is typically 84% (PUA-A), 80% (PUC-B) and 81% (PUB-M) all at full load. Input-to-output isolation voltage is 2,000V (PUA-A), 6,000V (PUC-B) and 3,000V (PUB-M).

The converters comply with safety standard EN/UL 62368-1 and the company is an ISO 9001/14001-certified supplier.

They are rugged for harsh industrial environments and have a mean time between failures (MTBF) rated at 17.9m hours (Mh) for the PUB-M, 15Mh for the PUC-B and 13.1Mh for the PUA-A.

Operating range is -40 to 100°C (PUA-A and PUC-B) and -40 to 110°C (PUB-M). Short-circuit protection is also included.

The PUA-A is supplied in an industry standard SIP4 device, measuring 11.5 x 6 x 10mm (0.45 x 0.23 x 0.36 inches), the PUC-B is in a SIP7 package (19.7 x 7.1 x 11.5mm / 0.78 x 0.28 x 0.45 inches), and the PUB-M is in a surface-mount device (12.75 x 11.2 x 6.6mm / 0.5 x 0.441 x 0.26 inches) for the single-output variant, and 15.25 x 11.2 x 6.6mm (0.6 x 0.441 x 0.26 inches) for the dual-output version.
