Features• System architecture based on transition mode boost PFC, half bridge LCC and

synchronous rectification (full bridge)• 270-480 VAC input voltage range• Output can be configured in constant current (CC) or constant voltage (CV)

mode:– 300 W maximum O/P power rating– CV mode: 48.5 V ± 1%– CC mode: 6.25 A ± 2.5% with voltage drop from 36 to 48 V

• 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:

– 0-10 V control– 1% resolution– analog dimming

• Soft start• Protections: I/P and O/P under and overvoltage protection, O/P open/no load

circuit protection, O/P short/overload circuit protection• Digitally controlled by STM32F334R8• RoHS compliant• WEEE compliant (2012/19/UE RAEE II)

DescriptionThe STEVAL-LLL009V1 digitally controlled 300 W power supply consists of powerfactor correction (PFC) and half-bridge LCC resonant converter power stages.An STM32F334R8 microcontroller implements DC-DC and output synchronousrectification digital control, while the PFC is driven in transition mode by the L6562ATcontroller. The system supports constant voltage (CV) and constant current (CC)operation.

MDmesh K5 and MDmesh DK5 Power MOSFETs are used in the PFC and LCChalf-bridge, respectively, to ensure maximum efficiency, while the STripFET F7 PowerMOSFET is employed to reduce conduction losses in the synchronous rectificationstage on the secondary side.

Both the primary and secondary sections are supplied by an off-line flybackcircuit based on VIPER267KDTR high voltage converter for ultra-wide input whichprovides regulated voltages to the control board, the gate driver ICs and the signalconditioning circuits.

Formal testing and measurement results confirm the ability and performance ofST power products combined with comprehensive digital control to deliver highefficiency, power factor near unity, and low THD across wide input voltage and loadconditions.

Note: The microcontroller ground is referenced to the power converter secondary side. The secondary side ground of the power converter and the grounddenoted by 0 are combined on the microcontroller daughter card.The analog and control signals ground are denoted by 0 to get star ground connection and reduce switching noise interference.
