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.
