Texas Instruments LM706A0-Q1 | Demoboard LM706A0QEVM

Description

The LM706A0QEVM high-density EVM is designed to use a regulated or non-regulated high-voltage input rail ranging from 8V to 65V to produce a tightly regulated output voltage of 3.3V at load currents up to 10A. This wide VIN range DC/DC device offers outsized voltage rating and operating margin to withstand supply rail voltage transients.The free-running switching frequency is 400kHz and is synchronizable to an external clock signal at a higher or lower frequency. The power-train passive components selected for this EVM, including buck inductors and ceramic input and output capacitors, are automotive AEC-Q200 rated and are available from multiple component vendors.
