# D2576DM-AD

**Silicore(芯谷)** · DC-DC Converters · ESOP-8

D2576DM-AD from Silicore(芯谷), in a ESOP-8. 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 IC switching regulator; a suitable input bypass capacitor must be present at this pin to minimize voltage transients and supply the switching currents, with recommended supply voltage 8V to 40V and absolute maximum supply voltage 42V. |
| 2 | Output | output | Internal switch output; steady-state output-to-ground voltage is limited to -1V minimum by the absolute maximum ratings. |
| 3 | Feedback | input | Senses the regulated output voltage to complete the feedback loop; on fixed-voltage versions it must be wired to the output voltage point, and on the adjustable version the programming resistors should not exceed 100 kΩ. |
| 4 | ON/OFF | input | Shuts the regulator down with logic-level signals: pulling this pin below approximately 1.5V turns the regulator on, and the pin can be wired to ground or left open for the regulator to be always on. |
| 5 | GND | power_in | Circuit ground. |
| 6 | GND | power_in | Circuit ground. |
| 7 | GND | power_in | Circuit ground. |
| 8 | GND | power_in | Circuit ground. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
