Function
Positive terminal of C1
Negative terminal of C1
Power supply voltage input
Power supply ground input
Negative terminal of C2
Current source outputs. Connect directly to LED
Current Sense Input. Connect 1% resistor to ground to set constant current through LED
Variable voltage input controls output current
Shutdown input. On LM2795, a high level inhibits device operation. Internal pull-up current
source allows open drain drive. On LM2794, a low level inhibits device operation
Positive terminal of C2
Charge pump output
(*) Note that the pin numbering scheme for the Micro SMD package was revised in April, 2002 to conform to JEDEC standard. Only the pin numbers were revised.
No changes to the physical location of the inputs/outputs were made. For reference purpose, the obsolete numbering had C1+ as pin 1, C1- as pin 2, VIN as pin
3, GND as pin 4, C2- as pin 5, D1-D4 as pin 6,7,8 & 9, Iset as pin 10, BRGT as pin 11, SD as pin 12, C2+ as pin 13, Pout as pin 14
