Function
No Connect
Power Ground (LLP Pins 2 & 3
must
be shorted
together).
Active-Low Shutdown Input
Frequency Adjust. An external resistor connected
between this pin and a voltage source sets the
switching frequency of the LM2623.
Output Voltage Feedback
No Connect
No connect
Signal Ground
Power Supply for Internal Circuitry
Bootstrap Supply for the Gate Drive of Internal
MOSFET Power Switch
Drain of the Internal MOSFET Power Switch. (LLP Pins
12 & 13
must
be shorted together).
No Connect
To be soldered to board for enhanced thermal
dissipation. To be electrically isolated/floating.
