It drives a single boost stage, switching the MOSFET on when the inductor current hits zero and off when it reaches the peak set by the error amplifier — this keeps the input current in phase with the line voltage without a dedicated multiplier. Supply voltage range is 10.3 V to 22 V, so it can be biased from an auxiliary winding on the boost inductor or from a separate 12 V or 15 V rail. The 50 µA startup current means the startup resistor sees negligible dissipation — a 100 kΩ resistor from the rectified DC bus drops about 5 mW while the controller is off. Operating temperature spans -25°C to 125°C, which covers industrial ambient conditions but not the full automotive range. The 125°C junction limit is the thermal design target — keep the copper area under the SO-14 package adequate to pull heat away from the die. ## Package and rework — can I swap it on site? It comes in a 14-SOIC (0.154\", 3.90 mm width) package, standard SO-14 footprint. The 1.27 mm pin pitch is wide enough that you can swap it with a soldering iron and flux if you have a steady hand — no hot-air station strictly required, though a preheater under the board helps avoid lifting pads. The tape-and-reel variant (L6563ATR) is the one you get from distribution in cut tape or full reels. If your BOM calls for the tube version (L6563A), the die is identical — just a different package delivery method. Both are surface-mount, same footprint, same electrical ratings. ## Lifecycle and sourcing — still active, no EOL worry ROHS3 compliant with no exemptions — no lead, no halogens above the threshold. The date code on the reel will be current production unless you specify a particular lot.","metaTitle":"STMicroelectronics L6563ATR PFC Controller, Transition Mode","metaDescription":"L6563ATR transition-mode PFC controller from STMicroelectronics.

The pinout is the same, so a board designed for the L6562A can be populated with the L6563ATR after verifying the protection thresholds match the system requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/L6563ATR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/L6563ATR when reusing this data.
