Pin Functions

PIN I/O DESCRIPTION
NAME NO.
MODE A1 IN This is the mode selection pin of the device. This pin must not be left floating and must be terminated.
MODE = Low: The device is operating in regulated frequency pulse width modulation mode (PWM) at high-load currents and in pulse frequency modulation mode (PFM) at light load currents.
MODE = High: Low-noise mode enabled, regulated frequency PWM operation forced.
VIN A2 IN Power supply input.
SW B1 IN/OUT This is the switch pin of the converter and is connected to the drain of the internal power MOSFETs.
EN B2 IN This is the enable pin of the device. Connecting this pin to ground forces the device into shutdown mode. Pulling this pin to VIN enables the device. This pin must not be left floating and must be terminated.
FB C1 IN Output feedback sense input. Connect FB to the converter’s output.
GND C2 – Ground pin.
