LM5114BSDEVAL
概覽
The LM5114 is a single low-side gate driver with 7.6A/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 LM5114 evaluation 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. The specifications of the evaluation board are as follows:
- Input Operating Voltage: 24V to 66V
- Output Voltage: 75V
- Output Current: 2A
- Measured Efficiency at 48V: 97% @ 2A
- Frequency of Operation: 500 kHz
- Line UVLO: 23.6V (Rising) /21.6V (Falling)
- Board size: 2.99 x 3.26 inches
The printed circuit board consists of 2 layers of 2 ounce copper on FR4 material, with a thickness of 0.050 inches.
