STMicroelectronics EVAL6563-80W

Overview

EVAL6563-80W from STMicroelectronics is an evaluation board implementing an 80 W active Power Factor Correction (PFC) pre-regulator based on the L6563 current-mode transition-mode controller, featuring active tracking boost functionality for wide-range AC input (90–265 VAC), delivering regulated DC output up to 390.6 VDC with >95% efficiency and PF >0.974 at full load.

For engineers reviewing the EVAL6563-80W datasheet, EVAL6563-80W pinout, EVAL6563-80W application, or EVAL6563-80W equivalent, this board enables rapid validation of tracking-boost PFC performance, THD optimization (<14.2% max), and dynamic output voltage regulation across universal mains inputs in lighting ballasts, industrial SMPS, and auxiliary power supplies.

Technical Context

The EVAL6563-80W implements a transition-mode (TM) boost PFC topology using the L6563 IC, where the output voltage dynamically tracks the RMS input voltage via resistor-programmed TBO pin biasing-enabling reduced conduction losses and improved light-load efficiency versus fixed-output designs.

It integrates a custom E25x13x17 ferrite inductor (3C85 core, 0.43 mH primary, 80-turn primary winding), line filter not EMI-certified, and delivers measured ripple <16.6 Vpk-pk at full load while maintaining PF ≥0.999 down to 90 VAC input.

FAQ

Is EVAL6563-80W still in production?

No. STMicroelectronics has marked EVAL6563-80W as obsolete per its January 2007 data brief. It remains available through authorized legacy distributors and Aetrix Electronics' extended-life inventory program with full traceability and documentation.

Can this board be used with other PFC controllers?

No. The EVAL6563-80W is specifically laid out for the L6563 IC, including pin-compatible layout, TBO pin routing, and inductor/compensation network values optimized for that controller's internal reference and gain structure.

What is the purpose of the TBO pin connection?

The TBO (Tracking Boost Output) pin (Pin 6 of L6563) accepts a resistor-to-ground to set the tracking ratio between Vout and Vin(RMS); on this board, it enables automatic Vout scaling from ~220 VDC at 90 VAC to ~391 VDC at 265 VAC, minimizing MOSFET voltage stress.

Does the board meet EMI compliance standards?

No. The included line filter is explicitly noted as "not tested for EMI compliance" in the data brief. System-level EMI filtering and shielding must be added per end-equipment requirements before certification testing.
