QW-R125-072.c
MULTIPLE IC PARALLEL SCHEMES (Cont.)
UL23EA
support multiple IC parallel schemes. No stroboscopic of color temperature application as shown in the
figure .If the output power is too large that the IC over temperature, Multiple IC parallel schemes can be adopted.
Typical Applications：RREXT1=RREXT3=RREXT5=20Ω，RREXT2=RREXT4=RREXT6=20Ω，
0.3S < Switching Period < 3S；
Open the switch for the 1st time，IOUT2=90mA；
Open the switch for the 2nd time，IOUT1= IOUT2=45mA；
Open the switch for the 3rd time，IOUT1=90mA；
When the switching period > 3S，System reset.
