TD1432PR
Techcode Semicon · DC-DC Converters · SOP-8
TD1432PR from Techcode Semicon, in a SOP-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 | VIN | power_in | Power input that supplies the IC and the step-down converter switches; drive with a 9V to 40V source and bypass to GND with a suitably large capacitor. |
| 2 | SW | power_out | Power switching output that is the switch node supplying the output; connect the output LC filter from SW to the load. |
| 3 | FB | input | Feedback input that senses the output voltage through a resistive divider, with a feedback threshold of 1.23V. |
| 4 | ON/OFF | input | Digital enable input where driving it low turns the regulator on and driving it high turns it off; do not leave it floating when Vin is above 32V. |
| 5 | GND | power_in | Ground pin for the device; pins 5 to 8 are all ground and should be connected to a maximized copper area for heat dissipation. |
| 6 | GND | power_in | Ground pin for the device; pins 5 to 8 are all ground and should be connected to a maximized copper area for heat dissipation. |
| 7 | GND | power_in | Ground pin for the device; pins 5 to 8 are all ground and should be connected to a maximized copper area for heat dissipation. |
| 8 | GND | power_in | Ground pin for the device; pins 5 to 8 are all ground and should be connected to a maximized copper area for heat dissipation. |
