6 Pin Configuration and Functions
QFN PACKAGE
Pin Functions
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| EN | 14 | I | Enable input. Pull high to enable the device, pull low to disable the device. |
| FB | 5 | I | Voltage feedback of adjustable versions, must be connected to VOUT on fixed output voltage versions |
| GND | 4 | Control / logic ground | |
| L1 | 11 | I | Connection for Inductor |
| L2 | 9 | I | Connection for Inductor |
| PS/SYNC | 1 | I | Pull to low for forced PWM, pull high for PWM/PFM (power save) mode. Apply a clock signal to synchronize to an external frequency. |
| PG | 2 | O | Open drain power good output |
| PGND | 10 | Power ground | |
| VIN | 12, 13 | I | Supply voltage for power stage |
| VOUT | 7,8 | O | Buck-boost converter output |
| VAUX | 3 | O | Connection for Capacitor of internal voltage regulator. This pin must not be loaded externally. |
| VSEL | 15 | I | Voltage scaling input. A high level on this pin enables a transistor which pulls pin FB2 to GND. |
| FB2 | 6 | O | Voltage scaling output. Connect a resistor from FB to FB2 to change the voltage divider ratio on the feedback pin. A logic high level on VSEL will change the output voltage to a higher value. Leave the pin open or connect to GND if not used. |
