Product details
Overview
STEVAL-VP26K01F from STMicroelectronics is an evaluation board implementing a three-output isolated flyback converter designed specifically for STCOMET-based smart meter and powerline communication (PLC) systems. It integrates the VIPER267KDTR 1050 V high-voltage offline controller, delivers 15 V/550 mArms, 5 V/100 mA, and 3.3 V/200 mA, and operates across 90–440 VAC input for phase-to-phase three-phase network compatibility.
For engineers reviewing the STEVAL-VP26K01F datasheet, STEVAL-VP26K01F application, STEVAL-VP26K01F schematic integration, or STEVAL-VP26K01F compatibility with STCOMET development kits, this board provides validated reference design, EMC-compliant operation per EN55022/EN61000 series, and plug-and-play use with VIPER267KDTR-based power supply validation.
Technical Context
The board implements a primary-side regulated, transformer-isolated flyback topology using VIPER267KDTR's integrated 1050 V avalanche-rugged MOSFET and 60 kHz jittered PWM control to reduce EMI. Feedback is achieved via optocoupler (SFH610A) and TL432-based secondary-side regulation for the 15 V rail.
A dedicated PM6644-based buck converter post-regulates the 15 V rail to generate tightly controlled 3.3 V/200 mA output, while a linear LDO (TS432ILT) regulates the 5 V/100 mA rail-enabling independent voltage stability for analog, digital, and PLC modem circuitry in smart metering applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 90–264 VAC nominal; supports up to 440 VAC overvoltage - enables direct phase-to-phase connection in 3-phase utility networks. |
| Output 1 (V1) | 15 V ±1 V at 550 mArms/700 mApeak - powers STCOMET PLC modem and analog front-end circuitry. |
| Output 2 (V2) | 5 V ±250 mV at 100 mA - supplies low-noise logic and interface circuits via TL432-based LDO regulation. |
| Output 3 (V3) | 3.3 V ±200 mV at 200 mA - generated by PM6644 buck converter from 15 V rail for digital subsystems. |

| Efficiency | 78.7% at full load - achieved through VIPER267KDTR's low standby power and optimized transformer design. |
| Ambient Temp | −40 °C to +85 °C - qualified for outdoor and uncontrolled indoor utility installation conditions. |

FAQ
What is the primary target application for STEVAL-VP26K01F?
The board is purpose-built for STCOMET-based smart meters and powerline communication systems. It supplies three isolated, regulated rails (15 V, 5 V, 3.3 V) to drive the PLC modem, analog signal chain, and digital subsystems under extended AC mains conditions (up to 440 VAC), meeting utility-grade reliability and EMC requirements.
Does STEVAL-VP26K01F require external programming or configuration?
No. The board is fully functional out-of-the-box with fixed feedback networks, optocoupler-based regulation, and hardwired PM6644 buck converter. No firmware, configuration tools, or host interface are needed-it operates as a standalone, self-contained power supply reference design.
Can STEVAL-VP26K01F be used without the STCOMET development kit?
Yes. The board functions independently as a three-output isolated flyback power supply. It can power any compatible 15 V/550 mA, 5 V/100 mA, and 3.3 V/200 mA load set. Its pin-compatible interface allows integration into custom PLC or metering hardware beyond the STCOMET ecosystem.
Which safety and compliance standards does STEVAL-VP26K01F meet?
The board meets EN55022 Class B (radiated/conducted emissions), EN61000-4-4 (electrical fast transient immunity), -4-5 (surge), and -4-6 (conducted RF immunity). It is RoHS and WEEE compliant, and its isolation barrier complies with reinforced insulation requirements per IEC 61000-4-5 for 4 kV surge protection.
