L6562N

Overview

The L6562N is a current-mode Power Factor Correction (PFC) controller operating in Transition Mode (TM), manufactured by STMicroelectronics. It is housed in an SOIC-8 or DIP-8 package and is designed for PFC pre-regulators compliant with IEC61000-3-2 standards. The device features a proprietary multiplier design to minimize Total Harmonic Distortion (THD) of the AC input current. Key electrical characteristics include an ultra-low start-up current of ≤70 μA, a low quiescent current of ≤4 mA, and an extended IC supply voltage range. It incorporates a -600/+800mA totem pole gate driver with UVLO pull-down and voltage clamp, alongside an on-chip filter on the current sense input.

Feature Summary

• Transition-mode control architecture for efficient PFC pre-regulation
• Proprietary multiplier design ensuring minimum THD of AC input current
• Ultra-low start-up and low quiescent current consumption
• Integrated on-chip filter on current sense input

Applications

• IEC61000-3-2 compliant SMPS for TVs, desktop PCs, and monitors up to 300W
• High-end AC-DC adapters and chargers
• Entry-level server and web server power supplies

Procurement Notes

Verify the specific suffix 'N' against the official datasheet to confirm package type and RoHS compliance status. Check the lifecycle status, as the L6562 series may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing PCB footprints for SOIC-8 or DIP-8 packages before procurement.

Selection Notes

Select this component for applications requiring transition-mode PFC control with strict harmonic distortion limits. Consider its pin-to-pin compatibility with the L6561 if upgrading from previous designs. Evaluate the extended supply voltage range and integrated gate driver capabilities against system requirements for cost-effective high-power factor correction solutions.

Part Context

The L6562 belongs to the L6562 family of PMICs focused on power management and PFC. It is realized in BCD technology and offers improved performance over the predecessor L6561. The device is part of STMicroelectronics' portfolio for AC-DC conversion, specifically targeting consumer electronics and entry-level server power supplies requiring efficient power factor correction.

Replacement Considerations

The L6562 is pin-to-pin compatible with the L6561. Verify if the L6561 serves as a direct substitute based on specific performance requirements and availability.
