STMicroelectronics EVL6562A-TM-80W

Overview

EVL6562A-TM-80W from STMicroelectronics is an 80 W transition-mode (TM) power factor correction (PFC) evaluation board built around the L6562A current-mode PFC controller and STP8NM50FP N-channel MOSFET. It delivers regulated 400 V DC output from 88–265 VAC input, achieves ≥92% efficiency at 90 VAC/80 W, maintains <10 V_pk-pk 2f_L output ripple, and supports 20 ms hold-up time down to 300 V - validated for flat-panel display power supplies.

For engineers reviewing the EVL6562A-TM-80W datasheet, EVL6562A-TM-80W schematic, EVL6562A-TM-80W application notes, or EVL6562A-TM-80W alternative evaluation boards, this page provides verified performance data, BOM-level component mapping, thermal and efficiency curves, and design-specific implementation guidance for TM-PFC pre-regulator validation.

Technical Context

The board implements a single-stage boost PFC topology using the L6562A controller in transition mode, where zero-current switching (ZCS) minimizes EMI and conduction losses. The controller senses input voltage via the MULT pin, inductor current via the CS pin, and regulates output voltage through the INV and COMP pins with internal 2.5 V reference.

It integrates a dedicated ZCD (zero-current detection) circuit to precisely trigger MOSFET turn-on at valley points, ensuring stable operation across 47–63 Hz line frequencies and enabling high PF (>0.95) and low THD (<10%) over full input range - confirmed by Figures 4 and 5 in the official data brief.

FAQ

Is EVL6562A-TM-80W still in production?

No - STMicroelectronics has marked EVL6562A-TM-80W as obsolete per its official data brief (Rev 2, October 2007). However, Aetrix Electronics maintains legacy inventory and offers technical documentation, BOM cross-references, and engineering support for ongoing maintenance and redesign projects.

What controller IC is used on this board?

The board uses the L6562A transition-mode PFC controller from STMicroelectronics, a current-mode IC with ZCD input, internal 2.5 V reference, and pin-compatible upgrade to L6562. It drives the STP8NM50FP MOSFET via the GD pin and regulates output using feedback from the INV pin.

Can this board be modified for higher output power?

Not directly - the board is optimized for 80 W with fixed inductor (0.7 mH), MOSFET (STP8NM50FP), and capacitor (47 µF/450 V) ratings. Increasing power would require re-rating the boost inductor, heat sink, bulk capacitor, current-sense resistor (R10/R9), and verifying ZCD timing; ST does not provide scalable design files for this evaluation board.

Does it include safety certifications?

No - EVL6562A-TM-80W is an evaluation board intended for lab use only and carries no UL, CE, or IEC safety certification. Its PCB layout, creepage/clearance distances, and component selection follow ST's reference design practices but are not certified for end-product compliance.
