CL1652A from ChipLink Tech, in a SOT-23-5. 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 | EN | input | Enable control, active high; it must not be left floating, and pulling it below 0.4V shuts the device down while above 1.5V re-enables it. |
| 2 | GND | power_in | Ground pin. |
| 3 | SW | output | Inductor pin; connect to the switching node of the inductor. |
| 4 | IN | power_in | Power supply input, operating from 2.7V to 5.5V. |
| 5 | FB | input | Output feedback pin; connect to the midpoint of the output divider to set the output voltage, Vout = 0.6 × (1 + R1/R2). |
