Product details
Overview
STEVAL-ISA030V1 from STMicroelectronics is a 6 W, 3-phase AC/DC switch-mode power supply evaluation board designed for metering applications, featuring primary-side regulation, 14 V / 430 mA output, >30 kHz switching frequency, and >80% efficiency across 150–850 VDC input range.
For engineers reviewing the STEVAL-ISA030V1 datasheet, STEVAL-ISA030V1 schematic, STEVAL-ISA030V1 application, or STEVAL-ISA030V1 equivalent, this board enables rapid validation of ESBT®-based high-voltage SMPS topologies in utility metering, industrial three-phase sensing, and low-power auxiliary supply designs with minimal external component count.
Technical Context
The board implements a flyback-derived, primary-regulated 3-phase SMPS using the L6565 quasi-resonant PWM controller and STC04IE170HP ESBT® (Emitter-Switched Bipolar Transistor) as the main power switch. It eliminates optocoupler-based secondary feedback by leveraging transformer auxiliary winding sensing and internal reference comparison.
Input rectification uses three STTH112U ultrafast diodes per phase, while output rectification employs STPS3L60U Schottky diode. The TL431_ARC provides precision voltage reference for regulation loop stability, and H11A817 optocoupler isolates feedback signals where needed for safety-compliant variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 150–850 VDC: supports full 3-phase rectified mains (e.g., 400 VAC line-to-line → ~565 VDC, up to 690 VAC → ~975 VDC), enabling direct use in global industrial metering inputs. |
| Output Power | 6 W continuous: sufficient for powering metrology SoCs (e.g., STPM3x), RTCs, communication modules (PLC, RF), and isolated sensors in Class 0.5/1 electricity meters. |
| Output Voltage/Current | 14 V @ 430 mA: regulated single-output rail optimized for driving isolated gate drivers, op-amps, and microcontrollers requiring stable bias under variable load and input conditions. |
| Switching Frequency | >30 kHz: avoids audible noise and enables compact magnetics; quasi-resonant operation reduces EMI and MOSFET/ESBT® switching losses. |
| Efficiency | >80% at full load: minimizes thermal stress in sealed meter enclosures and extends lifetime of electrolytic capacitors (C2–C4, C10–C11). |
| Regulation Method | Primary-side sensing: eliminates optocoupler and TL431 on secondary side in basic configuration, reducing BOM cost and improving long-term reliability vs. secondary feedback drift. |

FAQ
What is the primary regulation method used on STEVAL-ISA030V1?
The board implements primary-side regulation via auxiliary winding sensing on the main transformer (T1), feeding back voltage information to the L6565 controller's ZCD pin. This eliminates the need for optocoupler-based secondary feedback in standard configurations, reducing component count and improving long-term stability over temperature and time.
Can STEVAL-ISA030V1 operate directly from three-phase AC mains without external rectification?
No-it requires full-wave rectified DC input (150–850 VDC). The board does not include three-phase rectifier diodes; those are external. The schematic shows three STTH112U diodes (D1–D5) placed off-board, indicating it is intended for use after a discrete 3-phase bridge rectifier stage.
Which ST components are critical for its ESBT®-based topology?
The core active components are the STC04IE170HP ESBT® (Q1) as the high-voltage switching element and the L6565 quasi-resonant PWM controller (U1). Their co-design enables robust operation at high DC bus voltages with integrated zero-current detection and soft-start, essential for reliable metering PSU startup under wide input transients.
Is STEVAL-ISA030V1 compliant with IEC 62053 standards for electricity meters?
The board itself is not certified, but its architecture meets key requirements for IEC 62053-21/-22 auxiliary supplies: high input withstand (850 VDC), low no-load consumption (<150 mW typical), and stable 14 V output under line/load transients. Final system-level certification requires integration into a full meter design with appropriate creepage/clearance and EMC filtering.
