ZXLD1362ET5TA from Diodes Incorporated, in a TSOT-25. 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 NDMOS switch. Connects to the inductor and freewheel diode in the buck converter topology. Absolute max LX voltage -0.3 to +65V; continuous switch current 1A; RDS(on) typ 0.5Ω @ 1A.
2	GND	power_in	Ground reference (0V). All voltages in the datasheet are measured with respect to this pin.
3	ADJ	input	Multi-function On/Off and brightness control pin. Leave floating for nominal operation (VADJ = VREF = 1.25V, IOUTnom = 0.1/RS). Drive below 0.2V to disable output; drive with 0.3V-2.5V DC to set output current between 25% and 200% of nominal, or apply a PWM waveform (up to 1000:1 range) for LED dimming. A capacitor from ADJ to GND sets soft-start (~200µs/nF).
4	ISENSE	input	Current sense input. Connect resistor RS from this pin to VIN to define nominal average LED output current IOUTnom = 0.1/RS (VSENSE typ 100mV). RSMIN = 0.1Ω with ADJ pin open. Absolute max VSENSE = +0.3 to -5V (with respect to VIN).
5	VIN	power_in	Input supply voltage (6V to 60V operating; absolute max -0.3 to +65V). Decouple to GND with a 4.7µF or higher X7R ceramic capacitor placed close to the device. VIN > 16V recommended to fully enhance the internal output transistor.
