The LM5114BSDEVAL/NOPB is an Evaluation Board for LM5114, a single low-side gate driver with 7.6/1.3A peak sink/source drive current capability. It can be used to drive standard Si MOSFETs or enhancement mode GaN FETs in boost type configurations or to drive secondary synchronous FETs in isolated topologies. The board is designed to provide the design engineer with a fully functional boost DC-DC converter to evaluate the LM5114. A 100V enhancement mode GaN FET (EPC2001) is used as the boost power switch. The control circuitry is implemented with the LM5020, a 100V current mode PWM controller.
