STEVAL-ISA175V1

The STEVAL-ISA175V1 is an evaluation board implements a three output isolated flyback specifically designed to supply the STCOMET smart meter and power line communication system. The board is developed using the VIPER26HD offline high voltage converter by STMicroelectronics. The device features an 800V avalanche-rugged power section, PWM operation at 115KHz with frequency jittering for lower EMI, current limiting with adjustable set point, on-board soft-start, safe auto-restart after a fault condition and low standby power. The power supply is designed to operate across an extended 90VAC to 440VAC mains input voltage range to also be used with a phase-to-phase connection in a three-phase network. The board can be used in a stand-alone configuration or with the dedicated STCOMET development kit and the PCB layout is specifically designed to fit inside a real meter.

• Triple output voltage is 15V at 0.55Arms (0.7A peak), 3.3V at 200mA and 5V at 100mA
• Meets STCOMET smart meter and power line communication system specs
• EMC with EN55022, EN61000, EN61000-4-4, EN61000-4-5, EN61000-4-6
