Supply Voltage Input Pin. YB1682 operates from a 3.6V to 20VDC
voltage.
Bypass V
IN
to GND with a suitably large capacitor to eliminate noise
on the input.
Power Switch Output Pin. SW is the switch node that supplies
power to the output.
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 YB1682.
Feedback Pin. Through an external resistor divider network, FB
senses the output voltage and regulates it. The feedback threshold
voltage is 1.222V.
Enable Pin. EN is a digital input that turns the regulator on or off.
Drive EN pin high to turn on the regulator, drive it low to turn it off.
