Dear forum members;
For one of my project I need an isolated multipl output switching regulator.User supplies 24V DC. With this 24V I'm planning to control the temperature of a resistance with an ADuC834 mcu. Due to the noisy environment the dc 24V supply will be connected to ressistance and the mcu will control a SSR through an optoisolator. At mcu side I need +5V dc for digital part and +12V and -12V dc for some analog part. Due to the prices and availablity(in Turkey) instead of ready made solutions I'm planning to build the isolated converter myself with preferably LM25xx(they are available in Turkey)series switchers.
I'm new to isolated regulators and need some hints, application notes, books, reference designs from profesionals.
Best Regards
