Analog Devices Inc. EVAL-LT8306-AZ Evaluation Circuit demonstrates the features of the LT8306 micro-powered no-opto isolated flyback converter. The EVAL-LT8306-AZ outputs 12V and holds tight regulation with a load current from 15mA to 2.0A and over an input voltage from 6V to 36V. The output current capacity increases with the input voltage. The ADI EVAL-LT8306-AZ requires a minimum load (15mA) to regulate the output voltage because of the LT8306 ultra-low switching frequency at a very light load. A 13V Zener diode is positioned between the VOUT+ and VOUT- pins to limit the output voltage and avoid preloading under a no-load condition.
