NC Not Connect.
Supply Voltage Input Pin. TD1583 operates from a 3.6V to 28V
2
Vin DC voltage. Bypass Vin to GND with a suitably large capacitor
to eliminate noise on the input.
3
SW
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
4
GND
placed outside of the Schottky Diode to output capacitor ground
path to prevent switching current spikes from inducing voltage
noise into TD1583.
Feedback Pin. Through an external resistor divider network, FB
5
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
7
EN off.Drive EN pin high to turn on the device, drive it low to turn
it off.
