Texas Instruments TPS923650/1EVM Evaluation Modules

Texas Instruments TPS923650/1EVM Evaluation Modules offer a two-layer PCB assembly with multiple variants configured to evaluate the operation of the TPS923651/0. The TPS923651/0 is a 2A/1A non-synchronous Boost/Buck-Boost LED driver with a 4.5V to 65V wide input range with a PWM/analog dimming function.

The TI TPS923650/1EVM evaluation modules can drive LEDs with high power density and high efficiency by integrating a low-side NMOS.
