STEVAL-VP26K01F Data brief Three output isolated flyback converter for STCOMET smart meter and PLC system using VIPER267KDTR Features Triple output voltage: 15 V at 0.55 A (0.7 A peak), 3.3 V at 200 mA and 5 V at rms 100 mA Extended AC mains input voltage range: 90 to 440 V AC EMC with EN55022, EN61000, EN61000-4-4, EN61000-4-5, EN61000-4-6 WEEE compliant RoHS compliant Description The STEVAL-VP26K01F evaluation board implements a three output isolated flyback specifically designed to supply the STCOMET smart meter and powerline communication system. The board has been developed using the VIPER267KDTR offline high-voltage converter. The VIPER267KDTR 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 15 V at 550 mA (700 mA peak) to the power line rms modem (PLM) and the analog circuitry, a post-regulated 5 V at 100 mA and a 3.3 V at 200 mA supply through a dedicated DC-DC converter connected to the 15 V rail for digital circuitry and other low voltage parts. Product summary The power supply is designed to operate across an extended 90 to 440 V mains AC Three outputs input voltage range to be used also with a phase-to-phase connection in a three- isolated flyback phase network. converter for STCOMET smart STEVAL-VP26K01F The STEVAL-VP26K01F evaluation board can be used in a standalone configuration meter and PLC or with the dedicated STCOMET development kit. system using VIPER267KDTR 1050 V high voltage VIPER267KDTR converter 200 V, 2 A, high voltage power STPS2200U Schottky diode 100 V, 1 A SMA (flat), SMB power STPS1H100A Schottky rectifier 150 V, 1 A power STPS1150A Schottky rectifier Smart meter and powerline STCOMET communication system-on-chip 600 W TVS in SMA SMA6J100A-TR DB3881 - Rev 1 - May 2019 www.st.com For further information contact your local STMicroelectronics sales office.STEVAL-VP26K01F Features and specifications 1 Features and specifications Table 1.
