Product Details

The 20A LTC3871 power boards are power attachments for LT8740 Device power supply (DPS) evaluation boards. Each power board has two output voltage rails, Positive output voltage (VPOS) and Negative output voltage (VNEG), with voltage levels depending on the variant. Each rail can deliver a 20A current.

Note: The power boards can only deliver 20A, one voltage rail at a time, and are not evaluated simultaneously with both voltage rails sourcing 20A. See Table 1 in user guide for the three variants and their electrical specifications.
