SY5830BABC from Silergy Corp, in a SOT-23-6. 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 | ISEN | input | Current sense pin that connects to the source of the primary switch, with the sense resistor between that source and the GND pin (RS = k × VREF × NPS, k = 0.167); it also detects whether the transformer or secondary is shorted, and the current limit is 0.40-0.48 V with a 0.85-0.97 V protection limit for transformer short. |
| 2 | GND | power_in | Ground pin. |
| 3 | COMP | passive | Loop compensation pin where an RC network is connected across this pin and ground to stabilize the control loop, with a pre-charge value of 1.4 V. |
| 4 | VSEN | input | Inductor current zero-crossing detection pin that receives the auxiliary winding voltage through a resistor divider, provides line regulation modification, and triggers overvoltage protection when its voltage exceeds VVSEN,OVP (1.43-1.57 V). |
| 5 | VIN | power_in | Power supply pin, operating over 9.5 V to 27 V, which also provides output overvoltage protection together with the VSEN pin (VIN OVP 27-33 V). |
| 6 | DRV | output | Gate driver pin connected to the gate of the primary MOSFET, with a gate driver voltage of 9.5-13 V, maximum source current of 60 mA and minimum sink current of 250 mA. |
