Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | S/S | input | Shutdown/synchronization pin with an absolute maximum of -0.3V to 20V, a shutdown threshold of 0.45V to 1.2V, and external synchronization of the oscillator up to 500kHz. |
| 2 | FB | input | Feedback pin where the 1.22V to 1.26V reference voltage is measured, with an absolute maximum of VIN. |
| 3 | VC | passive | Compensation voltage pin with an absolute maximum of 3V. |
| 4 | GND | power_in | Ground pin of the device. |
| 5 | SENSE | input | Current sense input with an absolute range of -0.5V to VIN, where the current limit threshold is 40mV to 66mV (53mV typical). |
| 6 | GATE | output | Gate drive output for an external low side N-channel MOSFET, rated for a gate drive output current of ±1.5A absolute maximum (1A rail-to-rail driver). |
| 7 | DRV | power_in | Gate driver supply pin with an absolute maximum of -0.3V to 20V, operating from the input in nonbootstrapped mode or from the output in bootstrapped operation. |
| 8 | VIN | power_in | Input supply pin with an absolute maximum of -0.3V to 20V and an operating input voltage range of 1.9V to 18V. |
