Input voltage | 90-440 V |
Output 1 | 15 V / 0.55 A |
IC revision | V231 |
The STEVAL-ISA175V1 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 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.Although the power supply is designed to operate over a wide, 90-264 VAC input voltage range, it can also withstand a maximum AC main up to 440 VAC. The board can even operate with incorrect phase-to-phase connection in a three-phase network, though thermal performance would be worse.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
