Analog Devices Inc. EVAL-CN0509-EBZ Evaluation Board offers a wide input range of 5V to 100V with a USB charger capable of providing up to 2A at 5V from a wide range of DC sources. The EVAL-CN0509-EBZ Evaluation Board uses the combination of a wide input LTC7103 buck converter and an isolated flyback converter LT8302. The circuit accepts DC voltage from 5V to 100V and produces an isolated 5V supply via a standard USB connector. The circuit will survive up to 100V reverse connection to a power source with a green LED indicating correct input polarity and red led otherwise.
