Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CF2 | input | TRIAC or non-TRIAC mode detection input; a 1µF to 2.2µF capacitor is recommended, usually with a resistor in parallel to GND, and the absolute maximum rating is -0.3V to 3.6V. |
| 2 | BUS1 | passive | Internal compensation pin that requires a 2.2nF capacitor to GND; the absolute maximum rating is -0.3V to 25V. |
| 3 | IBLD | passive | Bleeding current pin that draws current from BUS to achieve good dimmer compatibility; the absolute maximum rating is -0.3V to 600V. |
| 4 | PVIN | passive | Drain of the integrated power MOSFET; the absolute maximum rating is -0.3V to 350V, and the MOSFET BV is 350V minimum. |
| 5 | VIN | power_in | IC power supply pin with a recommended operating range of 12V to 18V, an absolute maximum rating of -0.3V to 21V, and a supply current limit of 10mA. |
| 6 | VS | power_in | Source of the integrated power MOSFET used to sense output current; the absolute maximum rating is -0.3V to 3.6V. |
| 7 | CF | input | TRIAC angle detection input; the absolute maximum rating is -0.3V to 3.6V. |
| 8 | COMP | passive | Loop compensation pin where a 68nF to 100nF capacitor is suggested; the absolute maximum rating is -0.3V to 25V. |
| 9 | GND | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
