Regulator complies with CISPR 22 Class B
The output voltage of the LTM8073 µModule regulator is adjustable from 0.8V to 15V using a single resistor. This wide output range allows the regulator to generate common system bus voltages of 3.3V, 5V, 12V, and 15V. The part delivers 3A of output current at up to 85°C ambient without a heat sink or airflow, while paralleling two or more LTM8073s via a share pin produces higher currents. Efficiency at 24 VIN to 5 VOUT at 3A is 90%.
Housed in a 6.25×9×3.32 mm BGA package, the µModule integrates a switching regulator controller, power switches, inductor, and other supporting components. Only input and output filter capacitors and a few small resistors are required to complete the design. Switching frequency ranges from 200 kHz to 3 MHz. The regulator operates over a temperature range of -40°C to +125°C.
Prices for the LTM8073 start at $10.58 each in lots of 1000 units.
