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 XL4015.

Feedback Pin (FB). Through an external resistor divider

network, FB senses the output voltage and regulates it. The

feedback threshold voltage is 1.25V.

Power Switch Output Pin (SW). SW is the switch node that

supplies power to the output.

Internal Voltage Regulator Bypass Capacity. In typical system

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

Supply Voltage Input Pin. XL4015 operates from a 8V to 36V

DC voltage. Bypass Vin to GND with a suitably large

capacitor to eliminate noise on the input.
