2kVAC Isolated 1.5W Low Noise µModule Converters in
9mm x 11.25mm x 4.92mm BGA Package Are UL60950 Recognized
MILPITAS, CA – May 28, 2014 – Linear Technology Corporation introduces the LTM8057 and
LTM8058, 1.5W output µModule® (micromodule) DC/DC converters with 2kVAC galvanic
isolation (production tested to 3kVDC) in a 9mm x 11.25mm x 4.92mm BGA (ball grid array)
package. The LTM8057 and LTM8058 include an isolated transformer, control circuitry, power
switches and a modest amount of input and output capacitance. These µModule converters are
UL60950 recognized 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 –40ºC to
+125 ºC. 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. For more information visit,

* Pollution degree is a classification according to the amount of dry pollution and condensation present in the environment. This classification is
important as it affects parameters required to ensure safe operation of the product. Pollution degree 2 refers to an environment where normally only
non-conductive pollution or temporary condensation may occur such as offices, laboratories, test stations.
