This pin must be connected to the external resistor FB 1 Input divider (between VOUT and PGND) to adjust the output voltage. Forced COT or power save mode selection pin. Settings this pin high, the forced PWM mode is selected for every load current. Settings this MODE 2 Input pin low, PFM/PWM is selected, with the transition automatically occurring between the two operationing modes according to the load. This pin must not be left floating. Enable pin. Setting this pin high enables the device, while setting this EN 3 Input pin low shuts down the device. This pin must not be left floating. Input voltage. Place the input capacitor as close as possible to VIN VIN 4 Power and PGND. Power ground. It must be connected to the ground plane and to the PGND 5 Power exposed pad. Output voltage. Place output capacitors as close as possible to VOUT VOUT 6 Power and PGND. For thermal performance, use copper plane(s) at this pin. Exposed pad. This pin is internally electrically connected to PGND. It Exposed PGND EP is recommended to connect it to the ground plane for device heat Pad dissipation.
