Beschreibung
- 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 15V at 550mA rms (700 mA peak) to the power line modem (PLM) and the analog circuitry, a post-regulated 5V at 100 mA and a 3.3V at 200 mA supply through a dedicated DC-DC converter connected to the 15V rail for digital circuitry and other low voltage parts
