Product Overview

STEVAL-LLL009V1 digitally controlled 300 W power supply consists of power factor correction (PFC) and half-bridge LCC resonant converter power stages. An STM32F334R8 microcontroller implements DC-DC and output synchronous rectification digital control, while the PFC is driven in transition mode by the L6562AT controller. The system supports constant voltage (CV) and constant current (CC) operation.
  • System architecture based on transition mode boost PFC, half bridge LCC & synchronous rectification
  • 270-480VAC input voltage range
  • Peak efficiency >93.5%
  • Power Factor > 0.9 for load > 33% of max. load of the input voltage range
  • THD < 20% for load > 25% of max. load of the input voltage range
  • Dimming control in CC mode configuration
  • Soft start
  • I/P and O/P under and overvoltage protection, O/P open/no load circuit protection
  • O/P short/overload circuit protection
