IW1790-19B from RENESAS, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground connection for the controller; the datasheet gives no voltage limit for this pin. |
| 2 | SD | input | External shutdown input that can also be configured for external over-temperature protection by connecting an NTC resistor to ground; absolute maximum range is -0.3 V to 5.5 V. |
| 3 | VSENSE | input | Auxiliary voltage sense input used for primary-side regulation and transformer communication; absolute maximum range is -0.7 V to 10.0 V with IVsense ≤ 10 mA. |
| 4 | CFG | input | Input used for CDC configuration and auxiliary winding open protection; absolute maximum range is -0.7 V to 5.0 V. |
| 5 | ISENSE | input | Primary-side current sense input used for cycle-by-cycle peak-current control and the primary-side CV/CC limit; absolute maximum range is -0.7 V to 5.0 V. |
| 6 | SOURCE | power_in | Connects to the source of the external power MOSFET and internally to the MOSFET and the startup VCC charge circuit; absolute maximum range is -0.7 V to 25.0 V. |
| 7 | GATE | output | Gate drive output for the external MOSFET switch; absolute maximum range is -0.3 V to 30 V. |
| 8 | VCC | power_in | IC power supply pin; absolute maximum DC supply range is -0.3 V to 45.0 V, with a continuous DC supply current of 20 mA maximum. |
