The UCC25660EVM-064 assists designers to evaluate the operation and performance of the UCC25660 LLC resonant controller. This evaluation module (EVM) demonstrates how UCC25660 controls the LLC resonant half-bridge DC/DC converter to achieve high efficiency throughout the load and input voltage range. This EVM accepts DC input from 365V to 410V, AC input voltage from 85VAC to 264VAC and outputs 12VDC with 180W full load output power.

  • Enhanced light load management for low audible noise and low standby power
  • Integrated high-voltage startup and integrated gate drivers reducing total BOM count
  • Robust protection features including cycle-by-cycle current limit, over power protection, automatic capacitive region avoidance, overvoltage and overcurrent
  • X capacitor discharge function
  • Integrated PFC on/off control signal
  • Adaptive dead time
