DIO8650ECST6 from DIOO, 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 | CS | input | Current sense pin connected to the primary switch source, with the sense resistor between it and GND; also detects a shorted transformer or secondary, with 0.45 V current limit reference and 300 ns leading edge blanking. |
| 2 | GND | power_in | Ground pin. |
| 3 | COMP | passive | Loop compensation pin; connect an RC network between this pin and ground to stabilize the control loop. |
| 4 | ZCS | input | Inductor current zero-crossing detection input from the auxiliary winding resistor divider, also providing over voltage protection (threshold 1.5 V) and line regulation modification, with absolute maximum of -0.3 V to VIN+0.3 V. |
| 5 | VIN | power_in | Power supply pin with recommended 9.5 to 27 V range (absolute maximum 33 V), also providing output over voltage protection along with ZCS (30 V OVP). |
| 6 | DRV | output | Gate driver output connected to the gate of the primary MOSFET, clamped at 12 V with absolute maximum of -0.3 to 33 V. |
