Ambient Temperature Range
Power ground. Electrically needs to be connected to AGND.
Supply voltage input. When V
Reference connection for controller section. Also used as thermal connection for controller section.
Electrically needs to be connected to PGND.
The FB pin is used to determine the output voltage via a resistor divider between the output and
GND.
External loop compensation pin.
The enable pin is active HIGH. An internal pull-up resistor pulls EN pin to V
if it is left open.
PWM output connection to inductor.
Power good signal output pin. It is an open drain output used to indicate the status of output
voltages. This pin is internally pulled low when the output is below 90% of the nominal voltage.
