Pinout
12| Pin | Name | Functions | Notes |
|---|---|---|---|
| EN | Enable input | GPIO | Pull high to enable the device, pull low to disable |
| FB | Voltage feedback | ADC | For adjustable versions; must be connected to VOUT on fixed output voltage versions |
| GND | Ground | GND | |
| L1, L2 | Inductor connections | — | Connections for inductor |
| PS/SYNC | PWM/PFM mode selection | GPIO | Pull low for forced PWM, pull high for PWM/PFM (power save) mode; apply a clock signal to synchronize to an external frequency |
| PG | Power good output | GPIO | |
| PGND | Power ground | GND | |
| VIN | Supply voltage for power stage | — | |
| VOUT | Buck-boost converter output | GPIO | |
| VAUX | Connection for internal voltage regulator capacitor | — | Must not be loaded externally |
| VSEL | Voltage scaling input | GPIO | |
| FB2 | Feedback output for voltage scaling | — | Connect a resistor from FB to FB2 to change the feedback pin ratio; logic high on VSEL changes output voltage |
