MILPITAS, CA – December 12, 2011 – Linear Technology Corporation introduces the LTM8047 and LTM8048 1.5W output DC/DC µModule® converters with 725VDC galvanic isolation in a 9mm x 11.25mm x 4.92mm BGA (ball grid array) package. All components, including the transformer, control circuitry and power switches are housed in a small enclosed BGA package for superior interconnect reliability in high vibration applications. These compact and reliable products break ground loops in applications such as industrial, avionics and instrumentation equipment. Both devices operate from an input voltage of 3.1V to 32V, delivering a regulated output voltage on the secondary side, adjustable from 2.5V to 12V (LTM8047) and 1.2V to 12V (LTM8048). The LTM8048 includes a low noise linear post regulator that reduces the output ripple noise to 20µVrms at 300mA.
The LTM8048’s isolated post regulator delivers an output voltage accuracy of 2.5%. The low noise performance of the LDO delivers a clean supply rail, improving the performance of high accuracy mixed signal converters. Additional features available on both products include overcurrent protection and adjustable soft start.
The LTM8047 and LTM8048 are available for immediate delivery from stock 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. For more information, visit www.linear.com/product/LTM8047 and www.linear.com/product/LTM8048
