The TPS61054EVM-350 is a powerful evaluation module from Texas Instruments designed for the development of AC/DC and DC/DC converter designs for low power applications. This cost effective board makes testing, prototyping and validating design solutions more efficient. It is part of TI’s family of Evaluation Modules (EVMs) providing a consolidated and consistent approach to evaluating IC functionality. The TPS61054EVM-350 is part of their family of LED Drivers specifically designed for high brightness LED applications such as automotive lamps, consumer products, and general illumination.

The TPS61054EVM-350 evaluation module operates in buck-boost switching topologies, and is fully interoperable with the TPS5450 and TPS61054BAR chip packages. It includes an adjustable output voltage version and an adjustable current limit version. When using the adjustable output voltage version, the output voltage can be adjusted from 0.25V to 5.5V in increments of 0.25V. The adjustable current limiter limits the forward current to the LEDs within the range of 300mA to 1000mA. This is a versatile solution for lighting designs that require a simple and low cost scalability, such as automotive lamp applications.

The TPS61054EVM-350 module also features anintegral switching mode power conversion stage, wide input voltage range and adjustable LED forward current. It supports fast load transient response, adjustable protection thresholds and a short-circuit tolerant output. This modules comes with an optimized thermal design and offers an extremely high power density capability over a wide range of current and voltage levels.

The TPS61054EVM-350 evaluation module provides a comprehensive demonstration of the TPS61054 switching regulator performance. It includes four different test points providing input power (VIN), ground (GND), output voltage (VOUT) and current limit (IL). All test points can be used to measure the power stage performance of the TPS61054. Additionally, there are four LEDs located on each side of the board representing the forward current limit at each of the programmed levels.

The TPS61054EVM-350 evaluation module has an extended environmental range that covers temperatures from -40 up to +85 degrees C. It also features a full-protection suite with an integrated under/overvoltage protection, over/under current limit protection, a power-on reset, and a programmable hardware shutdown function. To make testing easier, TI also provides the TPS61054EVM-350 Application Software program that automates the process of testing and debugging the evaluation module.

The TPS61054EVM-350 evaluation module is a highly efficient platform for the design and testing of LED driver solutions. It offers a low cost and fast way to prototype, verify and validate any design. It is well suited for applications such as automotive lamps, consumer products, and general lighting solutions.
