Connect to logic supply through a resistor. High = power good; Low = power bad. If not used, leave unconnected. 2 EN I Enable input. High = On, Low = Off. A valid input voltage, on pin 8, must be present before EN is asserted. Do not float. 3 MODE I Mode selection input. High = forced PWM. Low = AUTO mode, with PFM at light load . Do not float. 4 FB I Feedback input to controller. Connect to output through feedback divider. 5 VOUT P Regulated output voltage; connect to COUT. 6 GND G Ground for all circuitry. Reference point for all voltages. 7 NC This pin must be left floating. Do not connect to ground or any other node. 8 VIN P Input supply to regulator. Connect to input capacitor(s) as close as possible to the VIN pin and GND pin of the module. EP EP G Ground and heat-sink connection. See Layout Guidelines section for more information.
