XB61040

XINLUDA · DC-DC Converters · SOT-23-5

XB61040 from XINLUDA, in a SOT-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 SW output Switch node. Connect the external inductor and Schottky diode to this pin. Internally connected to the drain of the N-channel power MOSFET; absolute-max voltage 30V.
2 GND power_in Device ground reference. Connect to the system ground plane.
3 FB input Feedback pin. Connect to an external resistor divider from VOUT to program the output voltage; internal reference VREF = 1.233V (typ). Absolute-max voltage VIN + 0.3V.
4 EN input Enable pin. Drive high to enable the converter; pull to ground to enter shutdown mode (supply current reduced to <1µA). VIH = 1.3V (typ), VIL = 0.4V (typ). Must not be left floating.
5 VIN power_in Supply voltage input. Operating range 1.8V to 6V; absolute-max 7V. Bypass to GND with a 4.7µF ceramic capacitor.
