3.2 Pin Definitions and Functions
Pin Symbol Function
1 IN
Input.
IC supply. For compensating line influences, a capacitor of 220 nF close to the IC pin is
recommended.
2 GND
Ground Reference.
Internally connected to Pin 5. Connect to heatsink area.
For thermal reasons both ground Pins 2 and 5 have to be soldered.
3 OUT
Output.
Block to GND with a capacitor close to the IC terminals, respecting capacitance and ESR
requirements given in the “Functional Range” on Page 7.
4 EN
Enable.
A low signal disables the IC. A high signal switches it on.
Connect to the input I, if the enable functionality is not required.
5 GND
Ground Reference.
Internally connected to Pin 2. Connect to heatsink area.
For thermal reasons both ground Pins 2 and 5 have to be soldered.
