ZXLD1350ET5TA from Diodes Incorporated, in a TSOT-23-5. 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 | LX | output | Drain of the internal 30V NDMOS switch. Connects to the switching node (inductor L1 and freewheel diode D1) of the buck converter. Rated 30V (40V for 0.5s transient), 500mA absolute max, RDS(on) typ 1.5Ω. |
| 2 | GND | power_in | Device ground (0V) reference. All voltages measured with respect to this pin unless otherwise stated. |
| 3 | ADJ | input | Multi-function On/Off and brightness control pin. Leave floating for nominal output current (VADJ = VREF = 1.25V, IOUTnom = 0.1/RS). Drive below 0.2V to turn output off; drive with DC 0.3V-2.5V to adjust output current 25%-200% of IOUTnom; drive with PWM (1%-100% at f<500Hz, 25%-100% at f>10kHz) for dimming; add a capacitor to GND to increase soft-start time (approx 0.5ms/nF). |
| 4 | ISENSE | input | High-side current-sense input. Connect sense resistor RS from this pin to VIN to set nominal average LED current IOUTnom = 0.1/RS (VSENSE threshold ≈ 100mV referred to VIN). RS minimum 0.27Ω with ADJ open. Input current typ 1.25µA. |
| 5 | VIN | power_in | Input supply voltage, 7V to 30V (40V transient for 0.5s). Decouple to GND with a 1µF or larger X7R ceramic capacitor placed close to the device. |
