Overview
The TPS62143RGTR from Texas Instruments is a high-efficiency synchronous step-down DC-DC converter designed for applications requiring high power density. This device is part of the TPS6214x family and is optimized for use in systems powered by a wide range of input voltages, including Li-Ion batteries and 12-V intermediate power rails. The converter features Texas Instruments' DCS-Control™ topology, which allows for high switching frequencies and fast transient responses. It is available in a compact 3-mm × 3-mm VQFN-16 package, making it suitable for space-constrained designs.
