Micro-module regulators rated for 2 kVAC IT systems isolation
They include an isolating transformer, control circuitry, power switches and other supporting components in a 9 x 11.25 x 4.92 mm BGA package. Only one resister, plus input and output capacitors are required to complete the design. Pin creepage and clearance and other features permit these devices to be recognized by UL60950 Information Technology Equipment Safety. The LTM8068 includes an additional low noise linear regulator. Applications include ground loop elimination in systems with sensors or noise sensitive loads in industrial automation, test and measurement equipment.
The LTM8067 and LTM8068 operate from an input voltage range of 2.8V to 40V in aflyback topology; each can regulate an output voltage above, below or equal to the input voltage. The LTM8067 has an adjustable output voltage range of 2.5V to 24V with up to 450 mA load current ability. The LTM8068, with a low noise linear regulator at its output, has an output voltage range of 1.2V to 18V. The linear regulator reduces the output voltage ripple to 20 µVRMS at 300 mA, improving the noise performance in powering high accuracy signal conditioning and mixed signal ICs.
The LTM8067 and LTM8068 operate from -40°C to 125°C and are priced at $10.90 (1000).
