L6561D013TR Présentation
A PFC controller is a power-management IC that shapes the current drawn from an AC input so that the input current is more closely in phase with the input voltage. In boost PFC, the controller drives a switching converter between the rectified mains input and a higher DC bus. The transition-mode control approach improves input-current shaping while supporting high power-factor power supplies used in industrial equipment, chargers, servers, and power-factor-correction front ends.
Key features reported for the L6561 family include an adjustable output-overvoltage protection function, a 50 uA typical startup current, a 4 mA typical operating supply current, an internal startup timer, an on-chip current-sense filter, an internal disable function, and a 1% internal reference at 25 C. The transition-mode PFC function is intended for wide-input applications where reduced harmonic distortion and controlled boost operation are important.
The L6561D013TR is supplied in an 8-pin SOIC package. Its suffix identifies the STMicroelectronics ordering configuration, while the D013TR part is associated with a 13 V nominal variant in the distributor data. Exact pin names, voltage limits, switching thresholds, timing values, and absolute maximum ratings should be confirmed from the official STMicroelectronics datasheet before final circuit design, because those parameters are not included in the supplied verification snippets.
Typical applications include AC-DC power-factor-correction stages for industrial and consumer power supplies, server or telecom power systems with active PFC, battery-charging front ends, and offline converters requiring harmonic-current reduction. The controller is normally placed around a boost switch, inductor, rectified input bridge, sensing network, and protection circuitry. Component values must be calculated from the target bus voltage, output power, input range, switching frequency, inductor ripple, and current-sense threshold.
A key design consideration is the interaction between the controller, boost inductor, MOSFET, rectifier bridge, and current-sense network. Keep the current-sense path short and shielded from high-dV/dt switching nodes, select the MOSFET and rectifier for the intended voltage and current stresses, and validate startup, overvoltage, line transients, and thermal behavior over the complete input range. This page combines verified distributor data, manufacturer information, replacement research, and practical design guidance.

Applications typiques
L6561D013TR convient pour 6 applications: Offline Industrial AC-DC Power Supply, Server and Telecom Power-Supply PFC Stage, Battery-Charging Power-Factor-Corrected Front End, Wide-Input Maintained Power Supply, Power-Factor-Corrected LED or Lighting Supply, Universal-Input Power Adapter.
Offline Industrial AC-DC Power Supply
The L6561D013TR fits an offline industrial AC-DC front end where the boost PFC stage must shape rectifier current and reduce input harmonics. Its transition-mode current control, adjustable output-overvoltage protection, internal startup timer, and on-chip current-sense filter help organize a robust boost PFC controller block. The exact output voltage, switching frequency, current-sense threshold, and compensation values must be selected from the official datasheet. The 8-pin SOIC package supports conventional surface-mount assembly while keeping the control circuit separate from the high-power switching path.
Recommandé
Server and Telecom Power-Supply PFC Stage
In server, telecom, and network-equipment power supplies, L6561D013TR can provide the control function for a boost PFC stage ahead of a downstream DC-DC converter. The controller's low operating supply current of 4 mA typical and startup current of 50 uA typical are useful for reducing standby burden, while its transition-mode architecture targets low input-current distortion. Design engineers must still verify harmonic-current limits, hold-up behavior, fault response, and bus-energy sizing for the specific AC input and output-power requirement.
Recommandé
Battery-Charging Power-Factor-Corrected Front End
The L6561D013TR can be used in battery chargers that require a regulated boost bus and improved power factor before a downstream charger stage. Its adjustable output-overvoltage protection provides a control point for protecting the intermediate bus when the load changes or the charger is disconnected. The actual charger design must account for input line transients, output capacitance, inductor saturation, MOSFET avalanche capability, and the battery chemistry's required voltage and current profile. The controller is not a battery-management IC by itself and does not replace charger-specific current regulation.
Recommandé
Wide-Input Maintained Power Supply
The L6561D013TR is suitable for systems operating across a broad rectified AC input range identified by STMicroelectronics as 85 V to 265 V. In a boost PFC topology, the controller helps shape current as the line voltage changes, which is important for universal-input adapters and industrial equipment. A universal-input design must separately validate the bridge rectifier, boost MOSFET voltage rating, inductor current rating, safety spacing, EMI filtering, and downstream output regulation. The 13 V suffix designation should be reconciled with the complete order-code datasheet before release.
Recommandé
Power-Factor-Corrected LED or Lighting Supply
In high-power lighting systems, the L6561D013TR can control the boost PFC stage that supplies a stabilized high-voltage DC bus before the lighting converter. The transition-mode control architecture is intended to improve input-current quality and reduce distortion, while the adjustable overvoltage function can help protect the bus during fault conditions. The system must include suitable PFC inductor, switching transistor, rectifier, input filter, output capacitor, and protection network. Confirm whether the target lighting product requires harmonic-current certification beyond the values available in the manufacturer overview.
Recommandé
Universal-Input Power Adapter
A universal-input power adapter can use L6561D013TR as the PFC controller in the boost stage that follows the AC bridge. The device's low-voltage control circuitry, transition-mode operation, internal startup timer, and current-sense filter help simplify the control section while maintaining PFC function. The final adapter still requires careful selection of the boost inductor and MOSFET, EMI filtering, isolated secondary circuitry, and feedback network. Verify the exact electrical limits, recommended application circuit, and thermal conditions from the official L6561 documentation rather than relying on distributor summaries.

- Integrated control features reduce external controller overhead (vs Generic discrete PFC control implementation)
Notes de conception
Place the L6561D013TR current-sense and feedback connections away from the boost-switch drain, gate-drive return, and high-current rectifier paths. Keep the current-sense loop short and use a compact, low-impedance layout for the sensing network. Because the controller measures low-level current-related signals, even a small high-DV/dt coupling can create timing errors or false protection events. Follow the official datasheet recommended layout and preserve the stated creepage and clearance requirements for the final mains voltage.
Select the boost MOSFET, inductor, rectifier, and output capacitor for the complete input range rather than the nominal 85 V to 265 V application range alone. Estimate inductor peak current from maximum line input, output power, duty cycle, ripple current, and the controller current-sense threshold. Validate MOSFET avalanche and switching-loss margin during line transients and validate that the inductor does not saturate at the highest expected load. The controller's 4 mA operating supply current does not represent the power dissipated by the external power stage.
Estimate thermal stress from the controller's actual supply dissipation and, separately, from the MOSFET, rectifier, inductor, and snubber losses. Use the manufacturer datasheet's absolute maximum ratings and recommended operating limits, then check junction temperature across ambient temperature, line frequency, line voltage, load, and startup duration. SOIC thermal performance depends strongly on copper area and neighboring components, so a package rating alone is not sufficient for a reliable production thermal design.
Do not substitute a generic L6561 or a cross-reference result solely because the product family names are similar. Confirm the exact orderable MPN, 8-pin SOIC package, pinout, current-sense polarity, UVLO, current-sense threshold, timing, protection behavior, and recommended compensation. The supplied web results identify L6562D and L6562ATDTR as same-pinout candidates, but exact package and parameter data for the alternatives must still be confirmed before production substitution.
Informations de conformité
The supplied verified snippets identify STMicroelectronics, L6561 application details, package information, and distributor sources, but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. Compliance must be confirmed from the current manufacturer product documentation and applicable distributor declarations.
