Overview
The TPS62163 from Texas Instruments is a part of the TPS6216x family of synchronous step-down DC/DC converters. These devices are optimized for applications requiring high power density and feature the advanced DCS-Control™ topology, which combines the benefits of hysteretic, voltage mode, and current mode control. This topology ensures excellent DC voltage regulation, superior load transient response, and very low output voltage ripple, making it suitable for systems sensitive to RF interference.
The TPS62163 operates over a wide input voltage range of 3 V to 17 V, supporting up to 1 A of continuous output current at output voltages between 0.9 V and 6 V. It is available in both adjustable and fixed output voltage versions and is packaged in a compact 2.00 mm x 2.00 mm 8-pin WSON package.
