PRODUCTION DATA
| PIN | TYPE | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | DGQ (Adjustable) | DGQ (Fixed) | ||
| EN | 6 | 6 | Input | Precision enable pin. Driving this pin higher than VEN(HI) enables the device. Driving this pin lower than VEN(LOW) disables the device. This pin can be left floating to enable the device because the device features an internal pullup current source. If this pin is tied to the IN pin then the input voltage must not exceed 18 V; see the Section 6.3 table. |
| FB | 2 | — | Input | Feedback pin. Input to the control-loop error amplifier for the (OUT) output. This pin is used to set the output voltage of the device with the use of external resistors. For adjustable-voltage version devices only. This pin must not be left floating. |
| GND | 5 | 5 | — | Ground pin. |
| IN | 10 | 10 | Input | Input pin. For best transient response and to minimize input impedance, use the recommended value or larger ceramic capacitor from IN to ground; see the Section 6.3 table. Place the input capacitor as close to the IN and GND pins of the device as possible. |
| MID_OUT | 8 | 8 | Output | MID output pin. A capacitor is required from MID_OUT to ground for stability. For best transient response, use the nominal recommended value or larger capacitor from MID_OUT to ground. Follow the recommended capacitor value as listed in the Section 6.3 table. Place the MID output capacitor as close to the MID_OUT and GND pins of the device as possible. |
| MVSEL1 | 4 | 4 | Input | MID_OUT voltage-select pin. The MVSEL1 pin and MVSEL2 pin are used to set the MID_OUT voltage; see Table 8-1 for details on how to set the MID_OUT voltage using these pins. Do not float this pin, instead tie this pin to GND if not used to set VMID_OUT. |
| MVSEL2 | 7 | 7 | Input | MID_OUT voltage-select pin. The MVSEL2 pin and MVSEL1 pin are used to set the MID_OUT voltage; see Table 8-1 for details on how to set the MID_OUT voltage using these pins. Do not float this pin, instead tie this pin to GND if not used to set VMID_OUT. |
| NC | 9 | 9 | — | No internal connection. This pin must be left floating to observe high voltage clearance between the IN and MID_OUT pins. |
| NC | — | 2 | — | No internal connection. This pin can be left floating or tied to the GND plane to improve thermal performance. |
| OUT | 1 | 1 | Output | Output pin. A capacitor is required from OUT to ground for stability. For best transient response, use the nominal recommended value or larger capacitor from OUT to ground. Follow the recommended capacitor value as listed in the Section 6.3 table. Place the output capacitor as close to the OUT and GND pins of the device as possible. |
| PG | 3 | 3 | Output | Power-good pin. An open-drain output indicates when the output voltage reaches VIT(PG, RISING). If not used, this pin can be left floating or tied to the GND plane to improve thermal performance. |
| Thermal pad | Pad | Pad | — | Exposed pad of the package. Connect this pad to ground or leave floating. Connect the thermal pad to a large-area GND plane for improved thermal performance. |
