LM2596HVS-ADJ from TECH PUBLIC, in a TO-263-5. 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 | VIN | power_in | Input supply voltage. Operating range 4.5V to 60V (absolute max 63V). Bypass locally with a 100 uF electrolytic and a 0.1 uF ceramic to GND. |
| 2 | OUTPUT | output | Switch (SW) output from the internal power transistor. Drives the external catch diode and inductor of the buck converter. Rated for 3 A load current; saturation voltage typ. 1.35 V at 3 A. |
| 3 | GND | power_in | Device ground. Tie to the system single-point ground/ground plane; keep return paths short to minimize switching noise. |
| 4 | FEEDBACK | input | Feedback input to the internal error amplifier. Regulates to VFB = 1.23 V (typ). Output voltage set by resistor divider: VOUT = VFB * (1 + R2/R1), with R1 between 1 kΩ and 5 kΩ. FB bias current typ. -70 nA. |
| 5 | ON/OFF | input | Active-low enable / shutdown input. Threshold VTH typ. 1.3 V (0.6 V min, 2.0 V max). Drive low (or leave floating with pull-down) for normal operation; drive high (>2.0 V) to enter low-power standby (~30 uA). Absolute max 60 V (or VIN). |
