UMW · DC-DC Converters · TO-263-5
LM2592HVS-5.0 from UMW, 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 | Positive input supply for the switching regulator, which needs a suitable input bypass capacitor placed at this pin to minimize voltage transients; supply range is 4.5V to 60V with an absolute maximum supply of 63V. |
| 2 | Output | output | Internal switch output that swings between (VIN − VSAT) and approximately −0.5V at a duty cycle of about VOUT/VIN, so the PC board copper connected to it should be kept to a minimum to reduce coupling to sensitive circuitry. |
| 3 | GND | power_in | Circuit ground for the regulator; external components should use a ground plane or single-point grounding as the datasheet recommends. |
| 4 | Feedback | input | Senses the regulated output voltage to complete the feedback loop; the pin voltage is rated from -0.3V to +25V. |
| 5 | ON/OFF | input | Shutdown input where pulling below about 1.3V turns the regulator on and pulling above 1.3V (maximum 25V) shuts it down, with the pin active low or left floating for the ON condition and total input current dropping to about 80 µA when off. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
