Symbol
Function
Converter enable input. A logic high enables the converter channel. A logic low
forces the channel into shutdown mode, reducing the channel supply current to less
than 1µA. This pin should not be left floating. When not actively controlled, this pin
can be tied directly to the source voltage (VIN1, VIN2).
Feedback input pin. For fixed output voltage versions, this pin is connected to the
converter output, forcing the converter to regulate to the specified voltage. For
adjustable versions, an external resistive divider ties to this point and programs the
output voltage to the desired value.
Signal ground. For external feedback, return the feedback resistive divider to this
ground. For internal fixed version, tie to the point of load return. See section on PCB
layout guidelines and evaluation board layout diagram.
Main power ground return. Connect to the input and output capacitor return. See sec-
tion on PCB layout guidelines and evaluation board layout diagram.
Output switching node that connects to the respective output inductor.
Input supply voltage. Must be closely decoupled to the respective power gnd.
Exposed paddle (bottom). Use properly sized vias for thermal coupling to the ground
plane. See section on PCB layout guidelines.
