and output voltage range. If this circuit is used for specified load only, it should be tuned by this
resistor to better efficiency and line regulation.
dimming frequency is about 200 Hz. For frequencies below 100 Hz the human eye will see the
flicker. The dimming function utilizes the NCP3065’s peak current protection input. The second way
to achieve this is to use the FB pin. See figure 10.
Conclusion
supply with wide input range (8-20V). The advantages of this circuit include its small size, low price,
wide input and output voltage ranges, and very small input current ripple.
and with current
The C4 coupling capacitor is selected based on input voltage and on current
and its minimal value is
The output capacitor’s current is
The value could be much larger for higher stability, but a higher value impacts the dimming
The resistor R8 is used to stabilize feedback loop. Used value is compromise for whole input
X1-3 input is used for dimming. The dimming signal level is 2-10 V. The recommended
This circuit is ideal in applications with strings of two to six LED chips powered from a power
