Introducing the DC1289A Demonstration Board from Linear Technology

The DC1289A is a state-of-the-art demonstration board from Linear Technology, designed to showcase the capabilities of the LTC®3880EUJ, a dual, polyphase synchronous step-down DC/DC controller. This product is engineered to cater to demanding applications that require precise voltage regulation and advanced power management features.

The LTC3880EUJ at the heart of the DC1289A is a marvel of power control, integrating digital power system management (PSM) that allows for real-time monitoring and control over a PMBus interface. This innovative controller supports telemetry functions that provide detailed information on voltage, current, temperature, and fault status, which is crucial for complex systems that require fine-tuned power adjustments and diagnostics.

Featuring a wide input voltage range of 4.5V to 24V, the DC1289A is versatile enough to handle a variety of power sources. Its output voltage can be precisely adjusted from 0.5V to 5.5V, making it suitable for a broad spectrum of applications, from industrial to high-performance computing environments. The board's ability to deliver up to 20A of output current per channel makes it an excellent choice for powering high-current devices such as FPGAs, ASICs, and microprocessors.

The DC1289A demonstrates the LTC3880EUJ's polyphase capability, which can effectively reduce input and output ripple, improve thermal performance, and increase power capacity by paralleling multiple channels. This is particularly beneficial in applications where space is at a premium and thermal management is critical.

Users of the DC1289A benefit from the rich feature set of the LTC3880EUJ, which includes accurate current sensing, programmable loop compensation, and active voltage positioning with variable gain and offset. Additionally, the board supports EEPROM data storage for fault logging and offers NVM protection for device settings.

With its robust design and advanced features, the DC1289A demonstration board is an excellent tool for designers and engineers looking to evaluate the performance and capabilities of the LTC3880EUJ controller. Whether you're working on a new power supply design or looking to upgrade an existing system, the DC1289A provides a reliable and efficient solution that simplifies the development process.
