Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS922054DMTR device is a 4A non-synchronous buck LED driver with a wide input range of 4.5V to 65V. By integrating a low-side NMOS switch, the device not only drives leds, but also charges batteries with high power density and efficiency. The series also supports common anode connections and single-layer PCB designs. The switching frequency can be configured in the range of 100kHz to 2.2MHz and has an optional spread frequency function for better EMI performance.
