Evaluation Boards - LED Drivers are electronic boards used as a quick and efficient way to test various kinds of electronic components, such as LEDs, motors, displays, and micro controllers. As such, it is important to consider evaluation boards and their associated application fields and working principles in order to make informed decisions when purchasing them. The TPS61158EVM-565 is a development board designed for driving high-current LEDs up to 1.5A with off-time PWM dimming and fast transient response. It is an excellent example of a typical evaluation board and its application field and working principle.

In terms of application fields, the TPS61158EVM-565 is an ideal solution for applications in LED lighting, LED sign displays, LED backlighting, LED outdoor lighting, and LED decorative lighting. In addition, the board can be used for other applications where the driving of multiple high-current LEDs at the same time is needed. It is also useful for testing and evaluating new designs for LED-based systems, prior to their commercial production.

The working principle behind the TPS61158EVM-565 is quite straightforward. It operates using an integrated, high-efficiency buck converter, which provides up to 1.5A with a maximum power dissipation of 8W. This buck converter is switched, regulated, and controlled by a single-port I2C bus, allowing the board to be connected to a host system so that commands can be sent to control the buck converter’s operation. Furthermore, the board also provides a programmable reference voltage, allowing the user to set a maximum brightness setting for the LEDs, as well as an over-temperature protection feature.

The TPS61158EVM-565 features ultra-fast transient response times, as well as variable off-time PWM dimming from 0 to 100% dimming range, with a maximum dimming frequency of 32kHz. This allows for smooth dimming and color mixing when connected to multiple strings of LEDs with different color temperatures. In addition, the board also provides an internally compensated, low-ripple current control and very tight voltage regulation.

Overall, the TPS61158EVM-565 evaluation board is a great and cost-effective option for testing and evaluating LED-based systems prior to their commercial production. With its integrated and highly efficient buck converter and features such as variable off-time PWM dimming, ultra-fast transient response, and low-ripple current control, this board is an ideal solution for LED applications in LED lighting, LED sign displays, LED backlighting, LED outdoor lighting, and LED decorative lighting.
