Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EXT/ | output | External transistor connection that drives the gate of the external switching transistor, with EXT/ pin voltage limited to -0.3 to VIN+0.3 V and EXT/ pin current limited to ±100 mA. |
| 2 | VDD | power_in | Power supply input, operating from 2.2 V to 10 V for the VOUT type, with an absolute maximum rating of -0.3 to +12 V. |
| 3 | GND | power_in | Ground reference for the controller; the datasheet notes that switching ground current can destabilize operation, so the GND pin surroundings should be strengthened. |
| 4 | CE | input | Chip enable input, with CE High at 0.65 V minimum and CE Low at 0.20 V maximum, where standby current is below 0.5 μA when CE is Low; the soft-start capacitor connection on this pin applies only to the C and D types. |
| 5 | VOUT (FB) | input | Feedback input for the externally set-up FB type (B and D), where the output is set by RFB1/RFB2 with the pin rated at -0.3 to VIN+0.3 V. |
