Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VS | power_in | Main supply pin for all internal biasing and auxiliary supply for the internal gate drive charge pump, with a recommended range of 5 V to 40 V; typically connected to VOUT or VIN, or a separate supply can be used. |
| 2 | GND | power_in | Ground return for the controller. |
| 3 | IN | input | Voltage sense connection to the external MOSFET source pin, with an operating input voltage range of 5 V to 40 V (1 V to 40 V with VS of at least 4.5 V when IN is below 4 V). |
| 4 | IN | input | Voltage sense connection to the external MOSFET source pin, with an operating input voltage range of 5 V to 40 V (1 V to 40 V with VS of at least 4.5 V when IN is below 4 V). |
| 5 | OUT | input | Voltage sense connection to the external MOSFET drain pin, with an operating output voltage range of 5 V to 40 V and 60 V transient capability. |
| 6 | OUT | input | Voltage sense connection to the external MOSFET drain pin, with an operating output voltage range of 5 V to 40 V and 60 V transient capability. |
| 7 | OUT | input | Voltage sense connection to the external MOSFET drain pin, with an operating output voltage range of 5 V to 40 V and 60 V transient capability. |
| 8 | OUT | input | Voltage sense connection to the external MOSFET drain pin, with an operating output voltage range of 5 V to 40 V and 60 V transient capability. |
