8.1 Application Information

The LMG1210 is designed to optimally drive GaN FETs in half-bridge configurations, such as synchronous buck and boost converters, as well as more complex topologies. By integrating the level shifting and bootstrap operation the complexities of driving the high-side device are solved for the designer.

The list below shows some sample values for a typical 48 V to 12 V application synchronous buck.

• Input Voltage: 48 V
• Output Voltage: 12 V
• Output Current: 10 A
• Bias Voltage: 6 V
• Duty Cycle: 25 %
• Switching Frequency: 1 MHz
• Inductor: 4.7 µH
