WD3168E-6 from WILLSEMI Will Semicon, in a SOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | power_out | Regulated 5V output voltage; supplies up to 300mA, output voltage range 4.8V-5.2V (VIN = 2.7V-5.5V, ILOAD = 50mA), 500mA current limit protection. |
| 2 | GND | power_in | Ground reference for all internal voltages; connect input, output, and flying capacitor returns as close as possible to this pin. |
| 3 | EN | input | Enable control input, active high; logic high threshold 1.3V, logic low threshold 0.4V, absolute max 5.5V; internal 2MΩ pull-down resistor allows pin to float for always-on operation. |
| 4 | CP- | passive | Negative terminal of external 1µF flying capacitor; connected to the bottom plate of the flying capacitor used by the x2 charge pump. |
| 5 | VIN | power_in | Input power supply; operating range 2.7V to 5.5V, absolute maximum 6V; bypass with 1µF (or 4.7µF for low-ripple) ceramic capacitor placed as close to pin as possible. |
| 6 | CP+ | passive | Positive terminal of external 1µF flying capacitor; charged from VIN during phase 1 of the two-phase non-overlapping clock, then stacked in series with VIN to VOUT during phase 2. |
