TD2596S50
Techcode Semicon · DC-DC Converters · TO-263-5
TD2596S50 from Techcode Semicon, in a TO-263-5. 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 | VIN | power_in | Power input that supplies the IC and the step-down converter switches; drive it with a 9V to 40V source and bypass it to GND with a suitably large capacitor. |
| 2 | SW | power_out | Power switching output node that supplies power to the output; connect the output LC filter from SW to the load. |
| 3 | GND | power_in | Ground reference pin for the device. |
| 4 | FB | input | Feedback input that senses the output voltage through a resistive divider; the feedback threshold is 1.23V. |
| 5 | ON/OFF | input | Digital enable input: drive low to turn the regulator on and high to turn it off; do not leave it floating when Vin is above 32V. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
