SY58237AGC from Silergy Corp, in a DIP-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 pin of the device. |
| 2 | ISEN | input | Current set pin, where a resistor programs the reference output current; the current reference is 300 mV typical (294 to 306 mV) and the absolute maximum rating is -0.3 V to 3.6 V. |
| 3 | VSEN | input | Voltage sense pin, connected to a resistor divider from the inductor or auxiliary winding to sense output voltage; the absolute maximum rating is -0.3 V to 16 V and the reference voltage is 1.5 V. |
| 4 | VCC | power_in | Power supply pin, with a turn-on threshold of 14 V, a turn-off threshold of 7 V, and an absolute maximum rating of -0.3 V to 20 V. |
| 5 | LX | passive | Internal high-voltage MOSFET drain pin, rated for a breakdown voltage of 650 V with RDSON of 3.4 Ω. |
| 6 | LX | passive | Internal high-voltage MOSFET drain pin, rated for a breakdown voltage of 650 V with RDSON of 3.4 Ω. |
| 7 | LX | passive | Internal high-voltage MOSFET drain pin, rated for a breakdown voltage of 650 V with RDSON of 3.4 Ω. |
| 8 | LX | passive | Internal high-voltage MOSFET drain pin, rated for a breakdown voltage of 650 V with RDSON of 3.4 Ω. |
