Question:
Why is the LT8471 Demo board DC1854A input range is limited to 32 V?
Answer:
The DC1854A was designed and qualified for an input voltage range between 6V to 32V so the data listed on the demo board manual is specifically for this test range. The LT8471 Dual Input DC/DC Converter features an absolute maximum input voltage of 50V and can operate above 32V as long as it does not exceed this maximum limit.
