STEVAL-VP26K02F Data brief Two output isolated SSR flyback converter for smart meter and PLC systems using VIPER267KDTR Features Double output voltage: 12 V at 0.7 A (1 A peak) and 6 V at 200 mA rms Secondary side regulation (SSR) Extended AC mains input voltage range: 85 to 500 V AC EMC with EN55022, EN61000, EN61000-4-4, EN61000-4-5, EN61000-4-6 WEEE compliant RoHS compliant Description The STEVAL-VP26K02F evaluation board implements a double output isolated SSR flyback 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 mA (1 A peak) to the power line modem rms (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 V but can also be connected to a single phase mains from 85 to 500 V .
