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 XL4012.
Feedback Pin (FB). Through an external resistor divider
network, FB senses the output voltage and regulates it. The
feedback threshold voltage is 0.8V.
Power Switch Output Pin (SW). SW is the switch node that
supplies power to the output.
No connected.
Supply Voltage Input Pin. XL4012 operates from a 5V to 32V
DC voltage. Bypass Vin to GND with a suitably large
capacitor to eliminate noise on the input.
