GM2500ACPZ-R7 from GONGMOSEMI, in a LQFN-12(2x2). 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 | AGND | power_in | Analog ground pin of the controller (模拟地). |
| 2 | EN | input | Precision enable pin: the device starts when the voltage rises above the 0.4 V enable threshold (50 mV hysteresis) and shuts down below it, and this pin must not be left floating. |
| 3 | VIN | power_in | Power input pin, which needs a low-ESR bypass capacitor placed as close as possible between this pin and PGND; the VIN operating range is 2.5 V to 5.5 V. |
| 4 | PGND | power_in | Power ground pin, to be soldered directly to the top-layer ground plane next to the VIN input capacitor. |
| 5 | SW | output | Switch node connected to the internal power switches and the inductor, which should be connected with short, wide traces; SW to PGND is rated −0.3 V to +6 V. |
| 6 | SW | output | Second switch node pin, tied to pin 5 and to the inductor with short, wide traces; SW to PGND is rated −0.3 V to +6 V. |
| 7 | PGND | power_in | Second power ground pin, to be soldered directly to the top-layer ground plane next to the second VIN capacitor. |
| 8 | VIN | power_in | Second power input pin, which needs its own low-ESR bypass capacitor placed as close as possible to this pin and PGND. |
| 9 | MODE/SYNC | input | Mode and clock-sync pin: grounded selects pulse-skip mode at light load, tied to VIN selects low-power mode, floating selects forced continuous mode, and an external square-wave clock synchronizes the switching frequency. |
| 10 | RT | input | Frequency-setting pin: tying to VIN selects the internal default of 2 MHz, while a resistor to ground sets 1 MHz to 3 MHz (or 3 MHz to 9 MHz for the high-frequency option), and the pin is ignored during external clock synchronization. |
| 11 | PGOOD | output | Power-good open-drain output that is pulled low when the output is outside the PGOOD threshold or above the overvoltage threshold, or when VIN is below UVLO, and requires an external pull-up. |
| 12 | FB | input | Feedback pin connected to the midpoint of the resistor divider between VOUT and AGND, with a typical regulated voltage of 0.5 V (0.495 V to 0.505 V for GM2500). |
| 13 | PGND | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
