STEVAL-VP26K01F

STEVAL-VP26K01F is an evaluation board that implements a three output isolated flyback specifically designed to supply the STCOMET smart meter and powerline communication system. The board uses the VIPER267KDTR offline high-voltage converter. The VIPER267KDTR features a 1050V avalanche-rugged power section, PWM operation at 60kHz with frequency jittering for lower EMI, current limiting with 700mA fixed set point, on-board soft-start, safe auto-restart after fault and low standby power. The power supply is designed to operate across an extended 90 to 440V AC mains input voltage range to be used also with a phase-to-phase connection in a three-phase network. The STEVAL-VP26K01F evaluation board can be used in a standalone configuration or with the dedicated STCOMET development kit.

• Triple output voltage: 15V at 0.55Arms (0.7A peak), 3.3V at 200mA and 5V at 100mA
• Extended AC mains input voltage range: 90 to 440V AC
• EMC with EN55022 and EN61000 standards
