MP6922DN-LF-P

Power Supply Controllers, Monitors Overview

The MP6922DN-LF-P is a dual fast turn-off intelligent controller designed for synchronous rectification in LLC resonant converters. It drives two N-channel power MOSFETs with a switching frequency of 100 kHz and operates within an input voltage range of 8 V to 24 V. The device features a shutdown function, non-isolated topology, and supports a maximum output current of 1 mA. It functions reliably across a temperature range of -40°C to +125°C and is housed in an SOIC-8E package.

Power Supply Controllers, Monitors Feature Summary

• Dual channel control for driving N-channel MOSFETs in synchronous rectifier applications
• Fast turn-off capability to minimize reverse recovery losses in LLC resonant topologies
• Integrated shutdown pin for system power management and efficiency optimization

Power Supply Controllers, Monitors Applications

• LLC resonant converter secondary side control
• Synchronous rectification in high-efficiency power supplies
• Server and workstation power distribution modules

Power Supply Controllers, Monitors Procurement Notes

Verify the suffix 'P' indicates tape and reel packaging versus 'Z' which typically denotes tube packaging, as this affects handling and assembly equipment compatibility. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the SOIC-8E footprint matches the PCB layout design specifications exactly to prevent soldering defects during surface mount assembly processes.

Power Supply Controllers, Monitors Selection Notes

Select this component when designing LLC resonant converters requiring precise gate drive timing for N-channel MOSFETs. The 100 kHz switching frequency suits medium-power applications where thermal management is critical. Compare against the MP6922DSE variant if higher switching frequencies or different package constraints are required for the specific power stage design requirements.

Power Supply Controllers, Monitors Part Context

This part belongs to the MP6922 series from Monolithic Power Systems, specialized for synchronous rectification. It complements primary-side controllers by managing the secondary-side MOSFETs. The DN designation specifies the SOIC-8E package, distinguishing it from other variants like the DSE (SOIC-8) or DS (SOIC-14) within the same functional family.

Power Supply Controllers, Monitors Replacement Considerations

MP6922DN-LF-Z is a direct functional substitute with identical electrical characteristics but differs in packaging format.
