TPS922054 Overview
The TPS92205x family is a 2A / 4A non-synchronous Buck LED driver with 4.5V to 65V wide input range. By integrating the low-side 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 anode connection and single layer PCB design.
