LM2576HVSX-ADJ from Texas Instruments, 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 | Supply input pin to collector pin of high-side transistor; connect to power supply and input bypass capacitors CIN with shortest possible path to high-frequency bypass and ground. |
| 2 | OUTPUT | output | Emitter pin of power transistor and switching node; attach to inductor and cathode of external catch diode. |
| 3 | GROUND | power_in | Ground pin; path to CIN must be as short as possible. |
| 4 | FEEDBACK | input | Feedback sense input pin; for adjustable version connect to midpoint of feedback divider resistor network to set output voltage according to VOUT = 1.23 V × (1 + R2/R1). |
| 5 | ON/OFF | input | Enable input to voltage regulator; high logic level = OFF, low logic level (below 1.2 V) = ON; connect to ground to enable regulator and do not leave floating. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
