HG2594M-5.0

HGSEMI · DC-DC Converters · SOP-8

HG2594M-5.0 from HGSEMI, in a SOP-8. 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 NC unconnected No connect. No internal function; leave floating or tie to ground per layout preference.
2 NC unconnected No connect. No internal function; leave floating or tie to ground per layout preference.
3 NC unconnected No connect. No internal function; leave floating or tie to ground per layout preference.
4 FEEDBACK input Voltage feedback pin. Senses the output voltage via a resistor divider network for regulation control. Internal reference threshold is 1.23V. For the fixed 5V version, this pin is tied directly to the regulated output.
5 ON/OFF input Switching enable pin (active-low). Tie to GND (logic low) to enable the regulator; drive high to disable/shutdown. Threshold approximately 0.8V (ON) / 1.4V (OFF). Floats to logic low by default.
6 GND power_in Ground pin. During PCB layout, route this pin to the output node ground path (past the Schottky diode) to keep switching current spikes out of sensitive nodes.
7 VIN power_in Supply input pin. Requires 4.5V-40V DC (60V on HV variants). Bypass with a high-value capacitor (e.g. 220uF/50V) between VIN and GND to suppress supply noise.
8 OUTPUT output Power switch output pin. Internal power transistor switching node that drives the external inductor/Schottky diode to deliver up to 1A to the load. Saturation voltage typ. 1.3V at 1A.
