# AP61100QZ6-7

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

AP61100QZ6-7 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; connect it to the resistive divider of the output (0.6V reference, VFB 0.588V to 0.612V in CCM). |
| 2 | GND | power_in | Power ground for the device. |
| 3 | VIN | power_in | Power input that supplies the IC and the step-down power MOSFETs; drive with a 2.3V to 5.5V source and bypass to GND with a suitably large capacitor. |
| 4 | SW | power_out | Power switching output node that supplies power to the output through the LC filter; DC voltage limit is -1.0V to VIN + 0.3V. |
| 5 | EN | input | Digital enable input: drive high (above 0.91V typical rising threshold) to turn the regulator on and low (below 0.83V typical falling threshold) to turn it off, and its level also selects PFM or PWM operation. |
| 6 | OUT | power_out | Output voltage power rail for the AP61100Q; connect it to the output load. |
