Pin Functions

PIN TYPE DESCRIPTION
NAME NO
VIN 3 Power VIN power supply pin
GND 4 Power GND supply pin
EN 5 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 2 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.
