📢 EEStar Reference Design Series: In this episode, we fully test the Leadtrend 240W GaN Fast Charger Reference Design, which supports the cutting-edge USB PD 3.2 EPR standard (5V-48V output).
We break down the technical architecture, including the LD7593DA PFC, the LD7710 AHB (Asymmetric Half-Bridge), and the LD6618CQM PD protocol controller. We also share the comprehensive efficiency and thermal test data collected under 120V and 230V input.
