Other Parts Discussed in Thread: TIDA-01427
Hello
I have built and used the below circuit to have two nearly symmetric voltages:
Vin= 5~5.5 Volt according to my design and real input power supply
I have considered Fsw=200KHz.
without any load the output voltages of the above circuit is around +/-6.8V
current through in my circuit are as following
Ip=360 mA and In=20 mA
so I measured the output voltages at the output of above circuit as Vp=4.8V and Vn=-6.7~-6.8V
when Ip=120mA the Vp is around 5~5.4V
what's the problem? I checked the equations and some datasheets before but I couldn't find a solution.
my time is a little restricted. I would be grateful if you could help me ASAP.
Best Regards
