概要
The STEVAL-VP26K03F evaluation board implements a double output isolated flyback with primary side regulation (PSR), specifically designed to supply smart meter and PLC systems.
The evaluation board has been developed using the VIPER267KDTR offline high-voltage converter, which features a 1050 V avalanche-rugged power section, PWM operation at 60 kHz with frequency jittering for lower EMI, current limiting with 700 mA fixed set point, on-board soft-start, safe auto-restart after fault and low standby power.
The power supply provides 12 V at 700 mArms (1 A peak) to the power line modem (PLM) and the analog circuitry, and 6 V at 200 mA to supply digital circuitry and other low voltage parts.
The power supply is designed to operate across a three-phase input mains from 50 to 290 VAC, but can also be connected to a single phase mains from 85 to 500 VAC.
