PRODUCTION DATA
PIN | TYPE(1) | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
VIN | 1 | PWR | Power supply input. Connect the input capacitor as close as possible between the VIN and GND pins. |
GND | 9 | PWR | Ground pin |
SW | 8 | O | This pin is the switch pin of the converter. This pin is connected to the internal power MOSFET and the inductor. Avoid connecting this pin to larger traces as this can increase EMI. This pin can stay unconnected or be soldered to a small pad for thermal improvement. |
PG | 7 | O | Open-drain power-good output with window comparator. This pin is pulled to GND while VOUT is outside the power-good threshold. This pin can be left open or tied to GND if not used. A pullup resistor can be connected to any voltage not larger than VIN. |
VOUT | 6 | PWR | Output voltage pin. This pin is internally connected to the integrated inductor. |
FB | 5 | I | Voltage feedback input. Connect the output voltage resistor divider to this pin. |
SS/TR | 4 | I | Soft-start, tracking pin. A capacitor connected from this pin to GND defines the output voltage rise time. The pin can also be used as an input for tracking and sequencing - see Voltage Tracking. |
MODE/SYNC | 3 | I | The device runs in PFM/PWM mode when this pin is pulled low. When the pin is pulled high, the device runs in forced PWM mode. Do not leave this pin unconnected. The MODE/SYNC pin can also be used to synchronize the device to an external frequency. See Synchronizing to an External Clock. |
EN | 2 | I | This pin is the enable pin of the device. Connect to logic low to disable the device. Pull high to enable the device. Do not leave this pin unconnected. |
