Product overview
Description
The STEVAL-ISA175V1 evaluation board implements a three output isolated flyback specifically designed to supply the STCOMET smart meter and powerline communication system.
The board is developed using the VIPER26HD offline high-voltage converter by STMicroelectronics. The device features an 800 V avalanche-rugged power section, PWM operation at 115 kHz 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 provides 15 V @ 550 mArms (700 mA peak) to the power line modem (PLM) and the analog circuitry, a post-regulated 5 V @ 100 mA and a 3.3 V @ 200 mA supply through a dedicated DC-DC converter connected on the 15 V rail for digital circuitry and other low voltage parts.
The power supply is designed to operate across an extended 90 to 440 VAC 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.
