The EVAL-ADM1278EBZ is a compact full feature evaluation board for the ADM1278. The board layout gives users a clear visual of all the peripheral components and the hot swap power path. The layout also maximizes the board’s ability to dissipate heat for some of the key components on the power path, allowing the evaluation of very high current hot swap setups.
Four sense-resistor slots and six multipackage FET slots give users great flexibility and allow a wide range of application setups.
Multiple test points allow easy access to all critical points/pins. Seven LEDs give users direct visual indication on variations in the board status, such as supply input, output, IC power good output, fault output, current sense output, and GPO outputs. An
AD7291 8-channel, I
2C, 12-bit SAR ADC allows users to measure voltage such as CSOUT and other pin voltages as well as to read ambient board temperature through an I
2C bus in real time.
The kit supports I
2C communication, allowing users to communicate with the ADM1278. The evaluation kit also supports cascade setup so multiple evaluation boards can be connected together and share the same I
2C bus.
The boards are fully compatible with the ADM1278 evaluation software tool, which can be downloaded from the ADM1278 product page.
Users need a USB-SDP-CABLEZ USB-to-I
2C dongle to use the evaluation software tools.
The standard evaluation kit is prepopulated and tested with a 12 V, 73A hot swap design capable of working with a 3 mF output capacitor.
Complete specifications for the ADM1278 are available in the
ADM1278 data sheet from Analog Devices and should be consulted in conjunction with this user guide when using the evaluation boards.
