LM2596MD5T-12

HGSEMI · DC-DC Converters · TO-252-5

LM2596MD5T-12 from HGSEMI, in a TO-252-5. 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 requiring a 4.5V~40V DC supply (60V for HV types), with a large capacitor placed between this pin and ground to suppress supply noise.
2 OUTPUT power_out Power switch output, the switching node that supplies the output load.
3 GND power_in Ground pin; in layout it should sit on the ground path at the output point away from the Schottky diode so switching current spikes do not inject noise.
4 FEEDBACK input Voltage feedback pin that monitors the output voltage through a resistor divider network for regulation, with a 1.23V threshold voltage.
5 ON_OFF input Enable pin where a low level turns the chip on and a high level shuts it down, defaulting to low when floating (high threshold 1.4V, low threshold 0.8V).
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
