Description

The power supply employs Full Bridge Resonant LLC with phase shift operating at ramp up, light load, low output voltage. This operating mode can replace PWM operating mode in LLC, which can improve efficiency signficantly in light load.

Features
  • Dynamic mode switching between frequency modulation to phase modulation
  • Maintains ZVS over a wider operating range
  • Enhanced monotonic control of the output over a wider operating range
  • Short-Circuit constant current operation
