Description
1 VIN
Supply Voltage Input Pin. XL7005 operates from a 5V to 65V
DC voltage. Bypass Vin to GND with a suitably large capacitor
to eliminate noise on the input.
2 SW
Power Switch Output Pin (SW). Output is the switch node that
supplies power to the output.
5~8 GND
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 XL7005. The exposed PAD is GND.
3 FB
Feedback Pin (FB). Through an external resistor divider
network, Feedback senses the output voltage and regulates it.
The feedback threshold voltage is 1.25V.
4 EN
Enable Pin. Drive EN pin low to turn on the device, drive it high
to turn it off. Floating is default low.
The Exposed PAD is GND
