Hi , I designed a smps with three different output using tny series IC. The three different outputs are 15volt, 18volt and 14 volt it's working. If I connect 20ohms load at the 15 volt output side the voltage is dropping to 14.8 volts. How can I avoid this ? 2. There are lot of spikes at my output side how can I avoid those spikes, 3. I connected lm1117 5 volt constant output ldo it's getting heat without load why it's getting so much heat ? Iused proper snuber circuit at my output side. Please help me to solve this issue
