Pin Functions
| PIN | TYPE(1) | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 1 | VIN | A | Input power pin |
| 2 | LDO | A | Output of internal LDO; connect a 1-μF decoupling capacitor between this pin and noise-free GND. |
| 3 | FSET | A | DC-DC (boost or SEPIC) switching frequency setting resistor; for normal operation, resistor value from 24 kΩ to 219 kΩ must be connected between this pin and ground. |
| 4 | VDDIO/EN | I | Enable input for the device as well as supply input (VDDIO) for digital pins |
| 5 | FAULT | OD | Fault signal output. If unused, the pin may be left floating. |
| 6 | SYNC | I | Input for synchronizing boost. If synchronization is not used, connect this pin to GND to disable spread spectrum or to VDDIO/EN to enable spread spectrum. |
| 7 | PWM | I | PWM dimming input. |
| 8 | NC | — | No connect |
| 9 | GND | G | Ground. |
| 10 | ISET | A | LED current setting resistor; for normal operation, resistor value from 24 kΩ to 129 kΩ must be connected between this pin and ground. |
| 11 | GND | G | Ground |
| 12 | GND | G | Ground |
| 13 | OUT3 | A | Current sink output; this pin must be connected to GND if not used. |
| 14 | OUT2 | A | Current sink output This pin must be connected to GND if not used. |
| 15 | OUT1 | A | Current sink output This pin must be connected to GND if not used. |
| 16 | FB | A | DC-DC (boost or SEPIC) feedback input; ; for normal operation this pin must be connected to the middle of a resistor divider between VOUT and ground using feedback resistor values between 5 kΩ and 150 kΩ. |
| 17 | PGND | G | DC-DC (boost or SEPIC) power ground |
| 18 | SW | A | DC-DC (boost or SEPIC) switch pin |
| 19 | NC | A | No connect |
| 20 | VIN | A | Input power pin |
