Texas Instruments TPS922050/1EVM Evaluation Modules
Texas Instruments TPS922050/1EVM Evaluation Modules offer a two-layer PCB assembly with multiple variants configured to evaluate the operation of the TPS922050/1. The TPS922051/0 2A/1A non-synchronous Buck LED drivers provide a 4.5V to 65V wide input range with a PWM/analog dimming function.
The TI TPS922050/1EVM evaluation module can drive LEDs with high power density and high efficiency by integrating a low-side NMOS.
