LM2596HVS-ADJ

TECH PUBLIC · DC-DC Converters · TO-263-5

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).
