Working Principles of TPS92075EVM2

The TMS92075EVM2 evaluation board combines the TMCS92075 LED driver, two FETs for high-side and low-side switching, two input terminals to control the output current, and two power MOSFETs for driving the LED strings. The TMCS92075 LED driver is a single-chip, constant current, buck LED driver that enables dimmable LED lighting solutions. The input voltage of the board is usually connected to an AC source. The TMCS92075 driver receives the input voltage and uses the onboard MOSFETs for the buck control. The TMCS92075 has two input terminals to control the output current. By controlling the voltage at these terminals, the output current can be adjusted and fine-tuned. With the appropriate input voltage and settings, the TMS92075EVM2 can provide a constant and predictable output current.Once the desired current is set, the TMCS92075 works by controlling the switching of the power MOSFETs. Depending on the input voltage, the MOSFETs switch off and on in an alternating pattern and regulate the current. This process, known as pulse width modulation (PWM), is used to effectively create a constant current, and the current can be adjusted by changing the PWM pattern.

The innovative and versatile TMS92075EVM2 is a highly advanced LED driver evaluation board that is suitable for a wide range of lighting applications. With its adjustable current settings, the TMS92075EVM2 enables dimmable LED lighting solutions with precise and predictable current control. The alternating buck control of the power MOSFETs, combined with adjustable terminal control, allows for an accurate LED power solution.
