2kVAC isolated µModule converters are UL60950 recognised

The LTM8057 and LTM8058 DC/DC converters are now available from Linear Technology, with both µModule devices featuring a 1.5W output and 2kVAC galvanic isolation (production tested to 3kVDC). Available in a 9 x 11.25 x 4.92mm BGA package, both devices include an isolated transformer, control circuitry, power switches and a modest amount of input and output capacitance.

These µModule converters are UL60950 recognised components under file #464570. Both devices operate from an input voltage range of 3.1V to 31V, delivering a regulated output voltage on the secondary side, adjustable from 2.5V to 12V (LTM8057) and 1.2V to 12V (LTM8058). The LTM8058 includes a low noise linear post regulator that reduces the output ripple to 20µVRMS at 300mA. Creepage and clearance distances support a working voltage up to 250V in a pollution degree 2 environment* for breaking ground loops in testers, servers, industrial automation, control and servo systems.

The LTM8057 maintains output voltage regulation accuracy of ±5% from -40°C to +125°C. The LTM8058’s linear post regulator improves output voltage regulation to ±2.5% over the same temperature range. Additionally, the post regulator delivers the advantage of a low output ripple noise, improving the performance of high accuracy mixed signal converters and precision operational amplifiers. High DC/DC conversion efficiency and diligent package design support full output power at ambient temperatures up to 110°C.

The LTM8057 and LTM8058 are available in three temperature grades, E and I from -40°C to +125°C and MP for the -55°C to +125°C operating junction temperature range. All versions are available from stock. Pricing starts at $10.90 and $11.45 each for 1,000-piece quantities for the LTM8057 and LTM8058, respectively.
