Description

Ground Pin. Care must be taken in layout. This pin should be placed outside of the Schottky Diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into XL4016.

network, FB senses the output voltage and regulates it. The feedback threshold voltage is 1.25V.

supplies power to the output.

application, The VC pin connect a 1uf capacity to VIN.

DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input.
