Texas Instruments LMR38020/LMR38020-Q1 Buck Converter

The Texas Instruments LMR38020/LMR38020-Q1 uses precision enable to provide flexibility by enabling a direct connection to the wide input voltage or precise control over device start-up and shutdown. With built-in filtering and delay, the power-good flag offers an accurate indication of system status, eliminating the need for an external supervisor. The device incorporates a pseudorandom spread spectrum for minimal EMI, and the switching frequency can be configured between 200kHz and 2.2MHz to avoid noise-sensitive frequency bands. In addition, the frequency can be selected for improved efficiency at a low operating frequency or a smaller solution size at a high operating frequency.

The device has built-in protection features such as cycle-by-cycle current limit, hiccup mode short-circuit protection, and thermal shutdown in case of excessive power dissipation. The LMR38020/LMR38020-Q1 is available in an 8-pin HSOIC PowerPAD package. The LMR38020-Q1 devices are AEC-Q100 qualified for automotive applications.
