Analog Devices' LT8390 60V Buck-Boost Controller Now at Mouser for Auto, Industrial and Battery Systems

March 7, 2018 - Mouser Electronics, Inc., the industry's leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the LT8390 synchronous buck-boost DC/DC controller from Linear Technology, now a part of Analog Devices, Inc. The LT8390 controller offers a 4 V - 60 V input voltage range and 0 V - 60 V output voltage range, making it ideal for voltage regulator, battery, and supercapacitor charger applications in automotive, industrial, telecom, and battery-powered systems.

The LT8390 DC/DC controller, available from Mouser Electronics, can regulate output voltage and input or output current from input voltages above, below, and equal to the output voltage. The device's four-switch buck-boost controller, combined with four external N-channel MOSFETs, can deliver from 10 W to over 400 W of power with efficiencies up to 98 percent.

The LT8390 uses a proprietary peak-buck, peak-boost current mode control scheme which uses a single inductor current-sense resistor to provide a seamless transition between buck, boost and buck-boost regions. The device delivers output voltage with ±1.5-percent accuracy, and its output current accuracy of ±3 percent ensures accurate constant current regulation. The LT8390 can be programmed to use a fixed switching frequency between 150 kHz and 650 kHz with synchronization, or it can utilize internal spread spectrum operation for lower electromagnetic interference (EMI). Additional features include an input or output current monitor, power good flag, integrated bootstrap diodes, and short-circuit protection with fault reporting. 

The LT8390 controller is available in either a 28-lead QFN or thermally enhanced 28-lead TSSOP package to provide a very compact solution footprint.
