SOT-23DBV Package(Top View)Table 5-1 Pin Functions
| PIN | TYPE(1) | DESCRIPTION | |
|---|---|---|---|
| NAME | NO | ||
| CB | 1 | P | Bootstrap capacitor connection for high-side FET driver. Connect a high quality 100-nF capacitor from this pin to the SW pin. |
| GND | 2 | G | Power ground pins. Connected to the source of low-side FET internally. Connect to system ground, ground side of CIN and COUT. The path to CIN must be as short as possible. |
| FB | 3 | A | Feedback input to the converter. Connect a resistor divider to set the output voltage. Never short this terminal to ground during operation. |
| EN | 4 | A | Precision enable input to the converter. Do not float. High = on, low = off. Can be tied to VIN. Precision enable input allows an adjustable UVLO by an external resistor divider. |
| VIN | 5 | P | Supply input pin to the internal bias LDO and high-side FET. Connect to the input supply and input bypass capacitors CIN. Input bypass capacitors must be directly connected to this pin and GND. |
| SW | 6 | P | Switching output of the converter. Internally connected to source of the high-side FET and drain of the low-side FET. Connect to the power inductor. |
(1) A = Analog, P = Power, G = Ground
