3.2 Pin Definitions and Functions
Pin Symbol Function
1CS2 Current Sense In 2
current monitor and power stage input
3CS1 Current Sense In 1
current monitor input
5I IC Supply
Place a capacitor from I (Pin 5) to GND close to the IC for compensating line
influences.
7CSO Current Sense Out
current monitor and status output
8EN Enable
high signal enables the regulator;
low signal disables the regulator;
connect to I, if the Enable function is not needed
10 GND Ground
connect pin to PCB and heat sink area
12 ADJ Voltage Adjust
connect an external voltage divider to configure the output voltage
14 Q Regulator Output
connect a capacitor between Q (Pin 8) and GND close to the IC pins, respecting the
values given for its capacitance C
Q
and ESR in the table Chapter 4.2
PAD
Heat sink
connect to PCB heat sink area and GND
