Input
This is the enable pin of the device. Pulling this pin to low forces the device into shutdown mode.
Pulling this pin to high enables the device. This pin must be terminated except for the
TPS622319, which has an integrated 1MΩ always active pull-down resistor.
SW

Output
This is the switch pin and is connected to the internal MOSFET switches. Connect the inductor to
this terminal
FB
6
Input
Feedback pin for the internal regulation loop. Connect this pin directly to the output capacitor.
MODE
1
Input
MODE pin = High forces the device to operate in PWM mode. Mode = Low enables the power
save mode with automatic transition from pulse frequency modulation (PFM) to pulse width
modulation (PWM) mode. This pin must be terminated except for the TPS622319 , which has an
integrated 1MΩ always active pull-down resistor.
(1)
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
(2)
All voltage values are with respect to network ground terminal.
