LM5000EVAL Non-Isolated Flyback Evaluation Module
The LM5000EVAL evaluation module (EVM) provides the design engineer with a fully functional non-
isolated flyback converter to evaluate the LM5000-3 high-voltage switch-mode regulator integrated circuit
(IC). The EVM provides 3.3-V output with 2-A current capability. The input voltage range is from 20 V to
55 V. This user's guide contains the electrical specification, quick setup procedure, performance curves,
application schematic, and bill of materials (BOM).
