DC-DC converters integrate transformer

14 November 2012 Power Electronics / Power Management

Linear Technology introduced the LTM8047 and LTM8048 1,5 W output DC-DC µModule converters with 725 V d.c. galvanic isolation in a 9 x 11,25 x 4,92 mm 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 3,1 V to 32 V, delivering a regulated output voltage on the secondary side, adjustable from 2,5 V to 12 V (LTM8047) and 1,2 V to 12 V (LTM8048).

The LTM8048 includes a low-noise linear post regulator that reduces the output ripple noise to 20 μVrms at 300 mA. This 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 over-current protection and adjustable soft start.
