MAX4983E Evaluation Kit
Power Supply (VCC)
The MAX4983E EV kit can be powered by the P1 USB
Table 4. Jumper JU3 Function
port (through the 3.3V LDO) or by an external power sup-
ply (VIN). The on-board MAX8511 linear regulator (U2)
provides the regulated 3.3V from the USB bus voltage
(5V) provided at P1. To evaluate the board with an exter-
nal supply, configure jumper JU3 according to Table 4.

DESCRIPTION
Device powered by on-board
linear regulator (3.3V)
Device powered by user-
supplied 2.8V to 5.5V power
supply connected to VIN and
with n-channel and p-channel MOSFETs, that routes the
P1 USB bus voltage (V1) to the P2 or P3 USB ports. The
power-switching circuit is controlled by the state of the
CB control pin, which is set through jumper JU1. See
Table 5 for operation.
