LMG5200 GaN 48V to 1V point of load evaluation module


Order now


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

  • Compliance, high-voltage warning documentation
