Shenzhen Mingjiada Electronics Co., Ltd [Supply] Texas Instruments LMR34215FAQRNXRQ1 4.2V to 42V, 1.5A Ultra-Small Synchronous Buck Converter Designed for Automotive Applications.

Description Of LMR34215FAQRNXRQ1

The LMR34215FAQRNXRQ1 regulator is an easy-to-use synchronous step-down DC/DC converter. The device features integrated high-side and low-side power MOSFETs to provide output current over a wide input voltage range of 4.2V to 42V.

The LMR34215FAQRNXRQ1 uses a peak current mode control mechanism to provide excellent efficiency and output voltage accuracy.

Precision enable provides flexibility by supporting direct connection to a wide input voltage or precise control of device startup and shutdown. A power up flag with built-in filtering and delay provides a true indication of system status, eliminating the need for external monitors.
