ZXLD1615ET5TA

Diodes Incorporated · DC-DC Converters · TSOT-23-5

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.
