STMicroelectronics STEVAL-ILB010V1

Overview

STEVAL-ILB010V1 from STMicroelectronics is an evaluation board designed to demonstrate the STL13NM60N 600 V, 0.320 Ω typ., 10 A N-channel MDmesh™ II Power MOSFET in PowerFLAT™ 8x8 HV package. It implements a high-efficiency flyback converter for offline AC-DC power supplies up to 40 W, featuring primary-side regulation, adjustable output voltage (5–24 V), and integrated overvoltage/overcurrent protection.

For engineers reviewing the STEVAL-ILB010V1 datasheet, STEVAL-ILB010V1 pinout, STEVAL-ILB010V1 application, or STEVAL-ILB010V1 equivalent, this board supports rapid validation of STL13NM60N switching performance, thermal behavior under load, and control loop stability in isolated low-power SMPS designs - with emphasis on layout-dependent EMI, gate drive optimization, and transformer coupling efficiency.

Technical Context

The STEVAL-ILB010V1 implements a quasi-resonant (QR) flyback topology using the STL13NM60N as the primary switch, driven by the L6565E controller IC. It operates from universal AC input (85–265 V_AC) and delivers up to 40 W at 24 V/1.67 A with >85% peak efficiency and <100 mW no-load consumption.

Key design features include primary-side sensing via auxiliary winding feedback, programmable soft-start, frequency foldback during overload, and built-in brown-out detection. The board integrates all critical passive components - including ETD29 transformer, snubber network, and output rectification - enabling direct functional testing without external circuitry.

FAQ

What is the maximum output voltage adjustment range supported by STEVAL-ILB010V1?

The board supports output voltage adjustment from 5 V to 24 V DC via a single external resistor (R_FB) on the feedback divider. The L6565E controller uses primary-side sensing to maintain ±5% regulation across line and load variations without secondary-side components.

Does STEVAL-ILB010V1 include safety isolation certification documentation?

No. While the board implements reinforced isolation per IEC 60747-5-3 (creepage/clearance ≥8 mm, reinforced insulation), it is not certified to UL/EN 62368-1 or similar standards. Users must perform their own safety compliance testing for end-product certification.

Can the STL13NM60N on this board be replaced with another MOSFET?

Yes, but only with compatible 600 V, PowerFLAT™ 8x8 HV packaged N-channel MOSFETs having R_DS(on) ≤ 0.4 Ω and Q_g ≤ 30 nC. Pin-compatible alternatives require verification of gate drive strength, SOA curves, and avalanche ruggedness - especially under QR operating conditions.

Is transformer design data included with the evaluation board?

Yes. ST provides complete transformer specifications (ETD29 core, 3C90 material, 12+1:1:10 turns ratio, leakage inductance <25 µH) and winding instructions in UM1645 user manual. Bobbin pinout and interwinding insulation details are also documented.
