Control and Status Signals

BUS Signals

ISHARE

Bus signal used by the power supply for active current sharing. All power supplies con# gured in the system for n+n sharing will refer to this bus voltage inorder to

load share.

Voltage Range

The range of this signal for active sharing will be up to 8.0 V, which corresponds to the maximum output current.

SCL, SDA

Clock and data signals de# ned as per I2C requirements. It is recommended that these pins be pulled-up to a 2.2 kohm resistor to 3.3 V and a 100 pF decoupling

capacitor at the system side.
