Hello, I am currently trying to fix my CTEK MXS 5.0 charger that died on me. I have already identified a shorted SMD MosFET and am trying to decode another part which looks like a SOT223-4 device. The markings on this device looks like a D1131G or D113iG, and below that are the numbers 17-50. I tried searching online for information to no avail. The Aliexpress site shows a SOT223-4 part which it labels as an IC with the model number 17-50, but indicates it as "no longer available". May I humbly ask for help from anyone who knows what part this is?
