TPS923653 Overview
The TPS92365x family is a 2-A / 4-A nonsynchronous Boost / Buck-Boost LED driver with 4.5V to 65-V wide input range. By integrating the lowside NMOS switch, the device is capable of driving LEDs as well as charging batteries with high power density and high efficiency. The family also supports mon cathode connection and single layer PCB design.
