**Diodes Incorporated** · DC-DC Converters · SOT-563

AP61100Z6-7 from Diodes Incorporated, in a SOT-563. 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 | FB | input | Feedback sensing terminal for the output voltage that must be connected to the resistive divider of the output (see the Setting the Output Voltage section). |
| 2 | GND | power_in | Power ground pin for the IC and the power stage. |
| 3 | VIN | power_in | Power input that supplies the IC and the step-down power MOSFETs and must be driven from a 2.3V to 5.5V source, bypassed to GND with a suitably large capacitor. |
| 4 | SW | output | Power switching output node that supplies power to the output, with the output LC filter connected from SW to the output load. |
| 5 | EN | input | Digital enable input where a high level (above the 0.91V typical rising threshold) turns the regulator on and a low level (below the 0.83V typical falling threshold) turns it off, and the EN level also selects PFM or PWM operation. |
| 6 | OUT | power_out | Output voltage power rail that connects to the output load and must not be tied to GND, and may be left as a no-connect only when C3 is installed as in Figure 2. |
