This is the enable pin of the device. Pulling this pin to low forces the device into shutdown mode. EN 4 I Pulling this pin to high enables the device. This pin must be terminated. Exposed – – Must be soldered to achieve appropriate power dissipation. Should be connected to GND. Thermal Pad Feedback pin for the internal regulation loop. Connect the external resistor divider to this pin. In FB 3 I case of fixed output voltage option, connect this pin directly to the output capacitor. GND 6 P GND supply pin MODE pin = High forces the device to operate in fixed-frequency PWM mode. Mode pin = Low MODE 2 I enables the power save mode with automatic transition from PFM mode to fixed-frequency PWM mode. This is the switch pin and is connected to the internal MOSFET switches. Connect the external SW 1 O inductor between this terminal and the output capacitor.
