DESCRIPTION
SD
Logic low on SD pin shuts down the Current Source completely and decreases current consumption to less than 1uA
PWM/PSM
SYNC
Vin
Logic high =PWM mode, logic low =PSM mode. In PSM mode synchronous rectification is disabled.
Externally controlled synchronization signal. Logic high to low transition forces the clock synchronization.
If not used must be connected to Vin or logic high.
Input supply voltage
GND
Ground
R1
Included inside the package for fixed voltage. To be added externally for all self-selected voltages.
V_TP
Voltage test point. To test the minimum gap above VL.
R0
To be added externally for selected output current.
V_L
Output current. LED connection
