The TPS61089EVM-742 is a production-ready development tool designed to evaluate the performance of the TPS61089 synchronous buck converter. TPS61089EVM-742 is designed for applications in the DC/DC & AC/DC (Off-Line) SMPS. This evaluation board is designed to quickly and easily validate the power efficiency, small size and fast transient response characteristics of the TPS61089.

The TPS61089EVM-742 is based on the TPS61089 synchronous buck converter. It can reach a peak efficiency of 95% and has a 4.5 MHz switching frequency. It is designed with high-voltage start-up to eliminate the need of a start-up resistor. The TPS61089EVM-742 is a 3A converter that has an input voltage range of 4.5V to 28V and an output voltage range of 0.5V to VIN. The board is integrated with a power ON/OFF button to control the start-up state of the converter. This board also includes an optional output voltage adjust and a multi-function I2C interface. The TPS61089EVM-742 is certified with UL/CSA/VDE safety ratings and is also CE/FCC approved, making it compliant with international safety requirements.

The TPS61089 synchronous buck converter chip used on this evaluation board is designed for automotive applications such as automotive body control, powertrain, ADAS, and entertainment. It helps to reduce the size of the system, by removing the need of external components and boosting efficiency. This synchronous buck converter also supports outdoor lighting such as street lamps, and power tools like motors, thus reducing the number of components and weight. The output voltage can be adjusted using the I2C interface, enabling the output voltage to adapt to different load requirements. Other benefits of this chip include integrated loop compensation, optional external compensation and adjustable soft-start.

The working principle of the TPS61089EVM-742 is quite simple. Input power is applied to the DC/DC from an external power source and is then converted into a regulated output voltage depending on the output voltage selection. This is achieved by controlling the duty cycle of the buck converter using an internal error amplifier. This in turn controls the average current flowing into the output capacitor. The peak inductor current is regulated in order to maintain the output voltage and prevent the switch current from exceeding the set limit.

The TPS61089EVM-742 is a powerful evaluation tool that enables users to accurately measure and compare the performance of the TPS61089 synchronous buck converter. The integrated I2C interface allows users to program and monitor the output voltage and other parameters of the converter. The board is designed to meet the safety requirements of several international certifications, thus making it suitable for almost any application in the DC/DC & AC/DC (Off-Line) SMPS market. This evaluation board is a great choice for anyone looking to assess the performance of the TPS61089 synchronous buck converter.
