Description
Feedback input pin of the Error Amplifier. Connect a resistor divider from the converter ’s output
voltage to this pin to set the converter ’s output voltage.
Ground pin. Connect to thermal pad.
The drains of the internal MOSFETs. The output inductor should be connected to this pin.
Power input for the power stage
Input supply pin for internal bias circuitry. A 0.1 m F ceramic bypass capacitor is preferred to connect
to this pin.
Output of the Gm Amplifier and compensation node. Connect a series R ? C network from this pin to
GND for control loop regulation.
Exposed pad of the package provides both electrical contact to the ground and good thermal contact
to the PCB. This pad must be soldered to the PCB for proper operation.
