The LMG5200POLEVM-10 EVM is designed to evaluate the LMG5200 GaN power stage and the TPS53632G half-bridge point-of-load controller in a 48V to 1V application. This EVM implements the 48V-1V converter as a single-stage hard-switched half-bridge with current-doubler rectifier. The EVM supports input voltages from 36 to 75 Volts and output currents up to 50 A. This topology efficiently supports the high step-down ratio while providing significant output current and controllability.

• Input voltage from 36V to 75V
• Output from 0.5 Volts to 1.5 Volts at up to 50 A
• Switching frequency up to 1 MHz
• DCAP+ control architecture provides fast transient response

What's Included:

• EVM PCB
• Compliance, high-voltage warning documentation

80-V 10A Power Stage EVM - The LMG5200 EVM board is a small easy to use power stage with an external PWM signal. The EVM is suitable for evaluating the performance of LMG5200 power stage in many different DC-DC converter topologies. It can be used to estimate the performance of LMG5200 to measure efficiency. The module is capable of delivering a maximum of 10A of current however adequate thermal management (forced air, running at low frequency etc) should be followed to ensure that the temperature is not exceeded. The EVM is not suitable for transient measurements as it’s an open loop board. 

Features:

• Input voltage operates up to 80V
• Simple open loop design to evaluate performance of LMG5200
• VCC supply generated on board from a poorly regulated supply
• Single PWM  input on board for PWM signal with < 8ns dead time
• Kelvin sense capability for input and output to measure efficiency
