PRODUCTION DATA.
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NUMBER | ||
| CBST | 1 | I | Boot strap capacitor for the supply of high-side MOSFET driver. An external capacitor is required between the SW and CBST pins to provide supply voltage to the high-side MOSFET gate driver. |
| EN | 2 | I | This is the enable pin of the device. Connecting this pin to ground ( < 0.4 V ) forces the device into shutdown mode. Pulling this pin to high ( > 1.2 V ) enables the device. This pin must be terminated but not floating. |
| FB | 3 | I | Voltage feedback of adjustable output voltage. Connecting a resistor divider network from the output of the converter to the FB pin. Must be connected to VOUT on fixed output voltage version. |
| VIN | 4 | I | Supply voltage for the internal circuitry. |
| SW | 5 | I/O | Switching node of the boost regulator. It is connected to the drain of the internal low side power FET and the source of the internal high-side power FET. |
| GND | 6 | – | Ground pin. Return for the internal voltage reference and analog circuits, also the source terminal of the low-side FET switch. |
| VOUT | 7 | O | Boost converter output. |
