STMicroelectronics STEVAL-VP26K01F is a three output isolated flyback converter evaluation board specifically developed for power supply in STCOMET smart meter and powerline communication (PLC) systems. The evaluation board is based on the VIPER267KDTR offline high-voltage converter designed to efficiently manage power across an extended mains input voltage range from 90 to 440 VAC, covering single-phase and phase-to-phase connections in three-phase networks.
The power supply delivers multiple stable output voltages: 15 V at 550 mArms (700 mA peak) for powering the power line modem (PLM) and analog circuitry; a post-regulated 5 V at 100 mA and 3.3 V at 200 mA outputs via a dedicated DC-DC Converter connected to the 15 V rail, providing supply for digital circuitry and low voltage components. This setup ensures clean and isolated power suitable for sensitive metering electronics.
The VIPER267KDTR device integrates a rugged 1050 V avalanche power section and operates with PWM at 60 kHz, using frequency jittering techniques to reduce electromagnetic interference (EMI). Additional features include a fixed current limit of 700 mA, on-board soft start circuitry for smooth power ramp-up, and safe automatic restart capability after fault conditions, optimizing reliability and safety for embedded system applications.
The STEVAL-VP26K01F board can be operated either as a standalone power supply or within the STCOMET development kit environment to facilitate comprehensive smart meter and PLC system design and testing. Its compliance with RoHS standards and country of origin being Italy underline its quality and environmental considerations.
The board supports a 90 to 440 VAC input voltage range suitable for single and three-phase networks. Provides 15 V at 550 mArms (700 mA peak) to power line modem and analog circuits. Includes post-regulated 5 V at 100 mA and 3.3 V at 200 mA outputs for digital circuitry.
Uses VIPER267KDTR device with 1050 V avalanche rugged power stage and PWM at 60 kHz. Features built-in current limiting, soft-start, low standby power, and auto-restart for faults. Designed for standalone use or in conjunction with STCOMET development kit.
This evaluation board is ideal for power management in industrial, smart metering, and PLC systems requiring isolated multiple voltage rails and high reliability.
