The devices are all isolating converters that provide output power of up to 1W, with no minimum load required.
Efficiency is typically 84% (pua-A), 80% (puc-B) and 81% (pub-M) at full load. Input-to-output isolation voltage is 2000V (pua-A), 6000V (puc-B) and 3000V (pub-M).
The converters are designed for the harsh environments found in industrial applications, and have mean time between failures (MTBF) rated at 17.9 million hours (Mh) for the pub-M, 15Mh for the puc-B and 13.1Mh for the pua-A.
The devices are safety compliant to EN/UL 62368-1, and Flex is an ISO 9001/14001 certified supplier.
Olle Hellgren, director of product management and business development at Flex, said: “These new DC-DC converters further expand our family of products for the industrial sector, all of which achieve high standards of performance, efficiency and reliability.”
The converters have an operating temperature range of -40 to 100°C (pua-A and puc-B) and -40 to 110°C (pub-M).
They include output short-circuit protection, to avoid damage.
The pua-A is a SIP4 device, measuring 11.5x6x10mm.
The puc-B is housed in a SIP7 package, measuring 19.7×7.1×11.5mm, while the pub-M is a surface-mount device with dimensions of 12.75×11.2×6.6mm for the single-output variant, and 15.25×11.2×6.6mm for the dual-output version.
