Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switching node that supplies power to the output; connect the output LC filter from SW to the load, with SW rated -0.3V to 44V absolute maximum. |
| 2 | BST | passive | Bootstrap pin for the top switch; a 0.1uF or larger capacitor must be connected between BST and SW, and BST is rated SW-0.3V to SW+5V. |
| 3 | BIAS/VD | power_out | Output of the internal LDO; a capacitor of 2.2uF or larger should be connected from VD to ground. |
| 4 | FB | input | Output feedback pin that senses the output voltage and is regulated by the control loop to 0.8V; connect a resistive divider at FB. |
| 5 | NC | unconnected | No connection. |
| 6 | GND | power_in | Ground; must be connected to the exposed pad and to pin 9 as close as possible. |
| 7 | EN | input | Drive high to turn the regulator on and low to turn it off; the device enters shutdown when EN is driven below 0.3V, and EN is rated -0.3V to 44V absolute maximum. |
| 8 | VIN | power_in | Input voltage pin supplying the IC; connect a 3.6V to 40V supply and bypass VIN to GND with a suitably large capacitor. |
| 9 | GND | power_in | Ground exposed pad; the pad and pin 6 must be connected to GND, and pin 9 must be connected to pin 6 as close as possible. |
