TD8202-S8AX from Shenzhen JingYang, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BS | passive | Bootstrap. Positive rail for the high-side switch gate driver. Connect a 0.01 uF capacitor between BS and SW. |
| 2 | VIN | power_in | Input supply, 4.5 V to 27 V. Bypass to GND with a low-ESR capacitor (>68 uF electrolytic recommended when Vin > 15 V). |
| 3 | SW | power_out | Switch output. Connect this pin to the switching end of the inductor. Absolute max range −0.3 V to Vin + 0.3 V. |
| 4 | GND | power_in | Ground return for the power stage and control circuitry. |
| 5 | FB | input | Feedback input. Voltage at this pin is regulated to 0.925 V (typ). Connect to the resistor divider between output and ground to set the output voltage. |
| 6 | COMP | passive | Compensation pin for the error amplifier. Connect an RC network to GND to stabilize the current-mode control loop (see Stability Compensation). |
| 7 | EN | input | Enable input. Higher than 2.7 V turns the IC on; below 1.1 V turns it off and discharges the output. Do not leave open - a 100 kΩ pull-up to VIN is recommended for start-up. |
| 8 | SS | passive | Soft-start control input. A capacitor from SS to GND sets the soft-start period (0.1 uF ≈ 15 ms, sourced by ~6 uA). Leave open to disable soft-start. |
