LMR14050SDDAR General Description

The LMR14050SDDAR is a synchronous step-down DC-DC converter manufactured by Texas Instruments. Operating with an input voltage range of 4.5V to 40V, it efficiently regulates output voltages as low as 0.8V. This converter is designed for applications requiring high efficiency and minimal power loss. With a maximum output current of 5A, it's suitable for various electronic devices, including industrial equipment, automotive systems, and consumer electronics. Featuring a fixed 500kHz switching frequency, it offers a balance between efficiency and component size. The device integrates MOSFETs to reduce external component count and simplify design. Its adjustable soft-start feature prevents inrush current during startup, enhancing system reliability. Furthermore, it incorporates thermal shutdown and current limit protection mechanisms, safeguarding against overheating and overload conditions. The LMR14050SDDAR is packaged in a thermally enhanced 14-pin WSON package, ensuring efficient heat dissipation and compact layout in space-constrained applications
