Bit[7:4] :
THL (3:0)
Main LED current Down transition per 0.2mA step
“0000” : 0.256 ms
“0001” : 0.512 ms
“0010” : 1.024 ms
“0011” : 2.048 ms
“0100” : 4.096 ms
“0101” : 8.192 ms
“0110” : 16.38 ms
“0111” : 32.77 ms
“1000” : 65.54 ms
“1001” : 131.1 ms
“1010” : 196.6 ms
“1011” : 262.1 ms
“1100” : 327.7 ms (Initial Value)
“1101” : 393.2 ms
“1110” : 458.8 ms
“1111” : 524.3 ms
Setting time is counted based on the switching frequency of Charge Pump.
The above value becomes the value of the Typ (1MHz) time.
Refer to page 34 “(8) Slope Process” of “ALC” for detail.
