Overview
The TPS2061CDGNR is a power-distribution switch from Texas Instruments, part of the TPS20xxC family. This component is designed to handle heavy capacitive loads and short circuits, making it suitable for applications such as USB ports, laptops, desktops, and other consumer electronics. The TPS2061CDGNR operates in a constant-current mode when the output load exceeds the current limit threshold, ensuring predictable fault current under all conditions.
