Description
The AnD8400EB is a ready to use Evaluation Board to evaluate the Quad-Buck AnD8400 PMIC. Simply apply PVIN, then measure default settings of 0.7V on the 4 VOUT terminals. To change VOUT, adjust the resistor divider ratio according to: R2 = Vfb * R1 / ( VOUT - Vfb) kΩ, or use the WebAdapter tool and select your desired VOUT. The tool reports will provide the resistor required location and value. Optionally, the Bucks may be modified as needed by the WebAdapter design tool and downloaded over the USB cable. The .HAX file downloads to the AnD8400 Adaptable PMIC while the .HEX file downloads to the flash memory. Functionality may be extended using On-Demand WebAmP tools.
Features
- Demonstrates AnD8400 Adaptable PMIC:
- Four 6A Synchronous Buck Regulators
- Four 0.2A auxiliary LDOs: 1.2V, 1.8V, 2.5V, 3.3V
- Sequencing
- WebAdapter™ or WebAmP™ Tool Downloads Configuration Files:
- .HAX file to configure the device directly
- .HEX file (Intel HEX) to program on-board flash
Typical applications
- Powering server, processor, memory, storage, network switcher and router platforms
- Powering FPGA, processor, SSD, subsystem power control & sequencing
- On-demand power management, multi-rail power integration
