Evaluation and Demonstration Boards and Kits

The BQ24018EVM (Evaluation and Demonstation Boards and Kits) (EVM) board was designed to demonstrate the capabilities of Texas Instruments\' high-power-density, full bridge, fully-differential, synchronous DC/DC converter—the BQ24018. The BQ24018 is a 5V/10A integrated synchronous DC/DC converter with a full bridge topology designed to provide high integration, low cost, and excellent power density for applications requiring a high output current level and a wide supply voltage range. The BQ24018 EVM provides a comprehensive evaluation platform for the BQ24018. This EVM board is designed to operate as a high-power density synchronous DC/DC converter.

The BQ24018EVM board provides the user with an adjustable power supply output of 0.6V to 5V with a maximum output current of 10A. With this adjustable output voltage and current level, it is possible to evaluate the BQ24018 along with various power supply topologies such as boost and flyback. Its wide input voltage range from 6V to 24V also enables the user to evaluate a wide range of applications.

The BQ24018EVM board is a two-layer PCB populated with a 30-MHz 8-bit microcontroller, a 2A master-slave integrated switch, a 4-channel analog-to-digital converter, 5 differential digital-to-analog converters, 4 feedback loop controllers, and four push buttons that can be used to control the converter. This board includes an isolated power module for regulation of the digital circuitry and provides the user with robust differential signals to ensure that noise does not disrupt the operation of the BQ24018.

The BQ24018 is a powerful synchronous buck DC/DC converter that can provide efficient power conversion from input voltages ranging from 6V to 24V. This synchronous buck converter uses a full bridge topology with PWM modulation to achieve better power conversion, thereby providing high efficiency and power density. In addition, the BQ24018 also offers an adjustable output voltage of 0.6V to 5V with a maximum output current of 10A, and a wide input voltage range of 6V to 24V.

The BQ24018 supports in-system programmability through its internal processor. This in-system programming can help to reduce development time by allowing the user to quickly and easily configure the converter to the desired voltage and current levels. The BQ24018 also integrates a low-loss current-mode control with a fast response time and a wide loop bandwidth, making it suitable for high frequency applications.

The BQ24018EVM is an excellent evaluation platform for the BQ24018 synchronous buck converter. With its adjustable output voltage and current, onboard microcontroller, and wide input voltage range, the BQ24018EVM provides the user with an extensive evaluation platform for testing the capabilities of the BQ24018 in various applications. Additionally, the onboard processor and in-system programming features make the BQ24018EVM an invaluable tool for development and testing.
