ZXLD1615ET5TA from Diodes Incorporated, in a TSOT-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 | LX | output | Output of the internal NDMOS switch, which switches the low side of the coil to ground. |
| 2 | GND | power_in | Ground (0V) reference pin, which the output capacitor should be placed close to. |
| 3 | FB | input | Feedback input for the voltage control loop, with a nominal regulation voltage of 1.025V. |
| 4 | EN | input | Enable input, active high to turn the device on, which also accepts a PWM signal to adjust output voltage; connect to VIN for permanent operation. |
| 5 | VIN | power_in | Input voltage supply of 2.5V to 5.5V, which should be decoupled with a capacitor close to the device. |
