Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Internal MOS drain and input supply pin; VIN maximum voltage is 60 V, with the stated input range up to 55 V. |
| 2 | VDD | power_in | Chip supply pin; VDD clamp voltage is 33 V, with undervoltage protection turning on at 4.5 V rising and off at 3 V falling. |
| 3 | FB1 | input | Positive output feedback voltage sense input; the FB1-FB2 reference voltage VFB is 369-391 mV (380 mV typical), and FB1/FB2/VCC/VSEN pin voltage is limited to -0.3 to 6 V. |
| 4 | FB2 | input | Negative output feedback voltage sense input; FB1/FB2/VCC/VSEN pin voltage is limited to -0.3 to 6 V. |
| 5 | VCC | power_out | Internal 5 V LDO output that requires an external capacitor; VCC voltage is specified at 5.5 V. |
| 6 | GND | power_in | Chip ground pin; output current limit resistor from VSEN to GND sets the maximum output current. |
| 7 | VSEN | input | Inductor current sense pin; the sense voltage VCS is 145-155 mV (150 mV typical) and the pin voltage is limited to -0.3 to 6 V. |
| 8 | Heatsink (EP) | power_in | Exposed heatsink pad, internally connected to the VIN pin. |
