Evaluation and Demonstration Boards and Kits have had a long history of providing innovative engineering solutions to the electronics and semiconductor industries. The BQ24002RGWEVM is an example of such a product. It is a single-channel DC-DC synchronous buck converter evaluation module with a high efficiency, wide input supply voltage range, and soft start capabilities.

The Evaluation Module, designed by Texas Instruments, is a two-stage, 4.5V-15V wide-input voltage one-channel synchronous buck converter. It provides a maximum output load current of 1.5A and over 90% peak efficiency. The E-mod is suitable for consumer and digital TV applications, POE adapters, and automotive infotainment devices.

The device’s high switching frequency enables small solution sizes and fast transient response times. The integrated non-overlapping MOSFET’s eliminate external components, providing faster design cycles and lowered development costs.

The BQ24002RGWEVM synchronous buck converter offers several unique features such as a low standby current of less than 0.1mΩ, an adjustable soft-start feature, an adjustable top-off charge voltage for trickle charge, and a thermal shutdown protection. Additional features include adjustable slope compensation for optimization of the light-load operation, output over voltage protection, and reverse current protection.

The evaluation module includes BQ24002 synchronous buck converter with an integrated thermal sensor, fault management, and failure detection circuitry, and an integrated input overvoltage protection circuit. It also has a wide input voltage range of 4.5V to 15V, and its bidirectional phase-shifted full-bridge architecture allows for bidirectional current flow.

The BQ24002RGWEVM operates in current mode control and offers a low output ripple voltage, low inductor current ripple, and fast transient response. Current mode control eliminates the need for loop compensation of the pulse width modulation controller, a feature that enhances design efficiency and decreases development time, making application of the module quicker and more convenient.

The evaluation module includes a comprehensive set of on-board LEDs, potentiometers, switches, and resistors for facilitating evaluation of the converter circuit and associated functionality. It also has an on-board USB-2 interface for software development and evaluation of the platform across a range of operating temperatures.

The Evaluation Module is a highly functional, compact, and energy-efficient solution that is tailored towards a variety of consumer and automotive applications. It provides optimized performance for high-power applications through wide input voltage range, low ripple current, fast transient response, and low standby current. With its unique features and comprehensive evaluation platform, the BQ24002RGWEVM Evaluation Module provides a cost-effective solution for today’s electronic and automotive applications.
