TPS92205x 2A/4A Non-Synchronous Buck LED Drivers Texas Instruments TPS92205x 2A/4A Non-Synchronous Buck LED Drivers have a 4.5V to 65V wide input range. By integrating the low-side NMOS switch, the devices can drive LEDs and charge batteries with high power density and high efficiency. The TPS92205x also supports common anode connection and single-layer PCB design. The switching frequency is configurable from 100kHz to 2.2MHz with an optional spread spectrum feature for better EMI performance.
