Flex Power Modules has extended its range of miniature 2W isolated, unregulated DC-DC converters for industrial applications

The PUB-2B series has single or dual output options with no minimum load required and is housed in a SIP7 package measuring 19.7 x 7.1 x 10.2 mm (0.78 x 0.28 x 0.4 in). The efficiency is typically up to 86% with a 12V output under full load conditions and the isolation between input and output is rated at 4kV

This follows the launch of the PUC-2B and PUB-2M families which also provide 2W of power but with 6kV isolation for teh PUC-2B in a SIP7 package and 3kV for the PUB-2M in a sufrace mount SMD package. Earlier this year, the company launched the PUA-A, PUC-B and PUB-M series of isolating converters intended primarily for industrial use delivering an output power of up to 1W and isolation voltages of up to 6kV.

This PUB-2B DC-DC converter has an MTBF of 18.3 Mhrs with enhanced protection for use in harsh environments common in industrial applications and operates in temperatures ranging from -40°C to +95°C. The devices are safety compliant to EN/UL 62368-1, and Flex Power Modules is an ISO 9001/14001 certified supplier.
