Dear all,
I want to know about 7 segment "LCD" dispay's characteristics. After searching everywhere i found no solution
1. Is Each segment of LCD works like "capacitor" ?
2. How to calculate capacitance?
3. Any equivalent circuit of it?
4. If i am driving LCD with general purpose IO than what...
Hello there,
I am designing push pull power supply with one input(20-366 VDC) to multiple (4) outputs.
1. 24V DC (35mA)
2. 5V(35 mA)
3. 13V(35 mA)
4. -13V(35 mA)
I used full wave rectifier. Now problem is....How to calculate values of filter capacitors for rectifier side and all output side...
Thanks Kappa_am,
I used flyback topology,
Specifications are as mentioned below.
Input range: 18-265VAC
Output1: 25VDC@110mA
Output2: -15VDC@30mA
Output1 & Output2 has common Ground1.
Output3: 13VDC@35mA
Output4: -13VDC@35mA
Output3 & Output4 has common Ground2.
Ground1 and Ground2 are...
Hello there,
I want to design a SMPS and that is all about AC to DC converter.
Now,
My requirement is
Input = 20-260 VAC or 38- 366 VDC
Output = 15V or 25 V @ 4W power....
So is there any transformer or circuit which can help me getting this specific value...???
Is any one there who knows???
