L6561D013TR

Overview

The L6561D013TR is a transition mode power factor corrector manufactured by STMicroelectronics, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 10 V to 28 V and functions reliably across temperatures from -40 °C to +150 °C. The device features a typical operating supply current of 25 mA and utilizes mixed BCD technology. It includes a disable function on the ZCD pin for standby optimization and provides a totem pole output stage capable of driving Power MOSFETs or IGBTs.

Feature Summary

• Integrated disable function on the Zero Current Detection (ZCD) pin to minimize current consumption during standby modes.
• Totem pole output stage designed to drive Power MOSFETs or IGBTs with high source and sink currents.
• Internal current sense filter eliminates the need for external low-pass filtering components.
• Precision internal reference voltage ensures accurate control performance across operating conditions.

Applications

• Wide input voltage AC-DC adapters
• Electronic lamp ballasts
• Switch-mode power supplies (SMPS)
• Inkjet printer power systems

Procurement Notes

Verify component authenticity through authorized channels as the part status is Not Recommended for New Designs (NRND). Confirm package integrity and moisture sensitivity handling requirements before assembly. Review official datasheets for specific ordering suffixes and environmental compliance details such as RoHS status. Ensure design-in compatibility with existing circuit topologies given the discontinued lifecycle status.

Selection Notes

Select this component for applications requiring wide input voltage operation and excellent total harmonic distortion performance. The integrated disable feature makes it suitable for systems demanding low standby power consumption. Consider the SOIC-8 package constraints and thermal management capabilities when designing PCB layouts. Evaluate the transition mode operation benefits against specific efficiency targets for AC-DC conversion tasks.

Part Context

This device belongs to the L6561 series, representing an improved version of the standard L6560 power factor corrector. It offers superior multiplier performance and reduced startup current compared to its predecessor. The series is optimized for electronic lamp ballasts and SMPS applications, providing enhanced functionality while maintaining full compatibility with standard designs.

Replacement Considerations

The L6561D is listed as a similar alternative to the MC34262D. Verify electrical parameter alignment and pinout compatibility before substituting other PFC controllers in existing designs.
