| PIN | I/O | TYPE(1) | DESCRIPTION | |
|---|---|---|---|---|
| NO. | NAME | |||
| 1 | EN | I | — | Active high driver enable |
| 2 | PXFR | I | — | Power transfer can be adjusted by selecting one of seven power level settings using an external resistor from the PXFR pin to VSSP. In three-wire mode, a given resistor setting sets the duty cycle of the power converter (see Table 8-1) and hence the amount of power transferred. In two-wire mode, a given resistor setting adjusts the current limit of the EN pin (see Table 8-2) and hence the amount of power transferred. |
| 3 | VDDP | — | P | Power supply for primary side |
| 4 | VSSP | — | GND | Ground supply for primary side |
| 5 | VSSS | — | GND | Ground supply for secondary side |
| 6 | VDDM | — | P | Generated mid supply |
| 7 | VDDH | — | P | Generated high supply |
| 8 | VDRV | O | — | Active high driver output |
(1) P = power, GND = ground, NC = no connect
