Pin Definitions and Functions IFX1963TBV

Pin

Symbol

Function

1EN

Enable;

A low signal disables the IC. A high signal switches it on.

Connect to the input IN, if enable functionality is not required.

2IN

Input voltage;

IC supply. For compensating line influences, a capacitor close to the IC pins is recommended.

3GND

Ground

4OUT

Output voltage;

Connect a capacitor between OUT and GND close to the IC terminals, respecting the values

given for its capacitance

5ADJ

Adjust Input;

Connect an external voltage divider from OUT to GND to determine the output voltage.

By connecting the output pin OUT directly to the adjust pin ADJ without resistors an ouput

voltage equal to the reference voltage
