PRODUCTION DATA
Figure 5-1 8-PinsUSIP Package (SIL)(Top View)| PIN | TYPE(1) | DESCRIPTION | |
|---|---|---|---|
| NUMBER | NAME | ||
| 1 | PG | O | Power-good flag; open drain. 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 Section 10.1 for more information. |
