製品概要
The EVAL-LTC4287-A1Z is a fully featured evaluation board for the LTC4287. The board layout provides a clear example of all the peripheral components and the hot-swap power path. The layout also maximizes the ability of the board to dissipate heat for some of the key components on the power path, allowing the evaluation of high-current hot-swap setups.
Eight sense resistor footprints and four (two on the bottom side) multipackage metal-oxide semiconductor field-effect transistor MOSFET footprints provide great flexibility and allow a wide range of application setups.
Multiple test points allow easy access to all critical points and pins. Seven light emitting diodes LEDs provide direct visual indication of board status, such as supply input, output, SDA, SCL, ALERT, power good, and fault.
The board supports PMBus™ communication, allowing the user to communicate with the LTC4287.
The board is fully compatible with the LTpowerPlay evaluation software, which can be downloaded from the LTpowerPlay page.
A USB-to-I2C controller (DC1613A) is required to use the evaluation software.
The standard evaluation kit is prepopulated and tested with a 54 V, 72 A hot-swap design capable of working with a 5 mF output capacitor.
Full specifications on the LTC4287 are available in the LTC4287 data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the EVAL-LTC4287-A1Z evaluation board.
