Application solutions instance
1 The PF value of 0.5 90% efficiency without
stroboscopic scheme
In the scenario above:
When LED series voltage of 270-285v, can do not need to buck capacitor C1,
when the LED lamp bead amount is small, by choosing appropriate
capacitance and regulate the flow of constant value, can achieve the best
power efficiency, suitable for 3-5 w light source module;
Capacitance C2 can for power supply filter, improve the average of the
power supply voltage, so as to improve the efficiency of power supply, but only
about 0.5 PF value of the whole machine;
Capacitor C3 main anti surge buffer effect, avoid IC moment is punctured,
improve product reliability;
Resistance RS can be used to adjust the LED constant current value,
specific see IC output current were calculated
