Flex Power Modules has extended its range of miniature isolated DC/DC converters aimed at industrial applications with the introduction of the PUB-2B series. Available in single or dual output options, the high-performance unregulated modules provide an output power of up to 2 W with no minimum load required. 

Housed in a compact SIP7 package measuring 19.7x7.1x10.2mm, the devices achieve a high efficiency, typically up to 86% with a 12V output under full load conditions. Isolation between input and output is rated at 4,000V.

The new family of isolated, unregulated DC/DC converter modules offers output short-circuit protection and MTBF figures of 18.3Mhrs. With enhanced protection for use in harsh environments common in industrial applications, the robust converters will reliably operate in temperatures ranging from -40 to +95°C. The devices are safety compliant to EN/UL 62368-1, and Flex Power Modules is an ISO 9001/14001 certified supplier.

The PUB-2B series launch closely follows the recent introduction of the PUB-2M and PUC-2B families which also deliver an output power of up to two watts. Input-to-output isolation voltage is 6,000V for the PUC-2B (presented in a SIP7 package) and 3,000V for the PUB-2M (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 one watt, and isolation voltages of up to 6,000V.
