DOINGTER · DC-DC Converters · TO-263-5L

DL6019 from DOINGTER, in a TO-263-5L. 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 GND power_in Ground pin.
2 EN input Enable pin: drive low to turn off the device (VEN threshold low 0.8V max), drive high (1.4V min) to turn on; floating is default high.
3 SW output Power switch output pin, the switch node that supplies power to the output, rated -0.3 to 60V; the metal tab is also SW.
4 VIN power_in Supply voltage input operating from 3.6V to 36V DC, to be bypassed to GND with a suitably large capacitor to eliminate input noise.
5 FB input Feedback pin with a feedback threshold voltage of 1.25V, rated -0.3V to Vin.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
