FB C1 I Output feedback sense input. Connect FB to the converter’s output. VIN A2 I Power supply input. This is the switch pin of the converter and is connected to the drain of the internal Power SW B1 I/O MOSFETs. This is the enable pin of the device. Connecting this pin to ground forces the device into EN B2 I shutdown mode. Pulling this pin to VI enables the device. This pin must not be left floating and must be terminated. 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 MODE A1 I (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. GND C2 – Ground pin.
