Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 MODE IN When the MODE pin is high, the device is forced to operate in PWM mode. When the MODE pin is low, the power save mode is enabled with automatic transition from PFM (pulse frequency mode) to PWM (pulse width modulation) mode. This pin must be terminated.
2 SW OUT This pin is the switch pin and is connected to the internal MOSFET switches. Connect the inductor to this pin.
3 VIN PWR VIN power supply pin.
4 GND PWR GND supply pin.
5 EN IN 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.
6 FB IN Feedback pin for the internal regulation loop. Connect this pin directly to the output capacitor.
