LM2592HVS-ADJ

HGSEMI · DC-DC Converters · TO-263-5

LM2592HVS-ADJ from HGSEMI, 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 that requires a DC source in the 4.5 V to 60 V range, with a large-value capacitor between the supply pin and ground to remove supply noise.
2 OUTPUT output Power switch output pin that acts as the switching node supplying the output load.
3 GND power_in Ground pin that must be routed so the output capacitor ground path stays outside the Schottky diode path, to prevent switching-current spikes from coupling noise into the circuit.
4 FEEDBACK bidirectional Voltage feedback pin that monitors the output through an external resistor divider and regulates it, with a feedback threshold of 1.23 V.
5 ON_OFF input Enable pin: applying a low level runs the chip and a high level shuts it down, and it defaults to low when floating.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
