STMicroelectronics STEVAL-VP26K02F Evaluation Board
STMicroelectronics STEVAL-VP26K02F Evaluation Board implements a double output isolated SSR flyback designed to supply smart meter and PLC systems. This evaluation board incorporates the VIPER267KDTR offline high-voltage converter that features a 1050V avalanche-rugged power section. The VIPER267KDTR converter also offers PWM operation at 60kHz with frequency jittering at lower EMI, current limiting with a 700mA fixed set point, and on-board soft-start. This VIPER267KDTR converter supports isolated flyback with an optocoupler, primary-side regulation, and non-isolated flyback with resistive feedback, buck, and buck boost SMPS topologies.
