MP6924AGS

Power Supply Controllers, Monitors Overview

The MP6924AGS is a dual synchronous rectifier controller designed for LLC resonant converters. It operates within a VDD range of 4.2V to 35V and supports CCM, CrCM, and DCM modes. The device features a fast turn-off delay of 35ns to prevent reverse current flow. It drives two N-channel MOSFETs with a typical forward voltage regulation of approximately 29mV. Static current in light-load mode is around 175µA. The component is housed in an SOIC-8 package and functions as part of the MP6924 series.

Power Supply Controllers, Monitors Feature Summary

• Fast turn-off capability minimizes reverse conduction losses by detecting zero-crossing points accurately.
• Dual-channel architecture enables high-side and low-side synchronous rectification for secondary windings.
• Light-load management locks the gate driver to reduce quiescent current during standby conditions.
• Integrated thermal protection automatically disables outputs when junction temperature exceeds safe limits.

Power Supply Controllers, Monitors Applications

• AC/DC adapters and laptop power supplies
• LCD and LED television power sources
• Isolated DC/DC converter modules

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix (P or Z) to confirm packaging type, as these affect handling and reel specifications. Ensure compatibility with the target LLC topology and MOSFET gate drive requirements. Confirm RoHS compliance status matches project environmental standards. Cross-reference the datasheet version to validate electrical parameters against current design constraints.

Power Supply Controllers, Monitors Selection Notes

Select this component for applications requiring precise timing control to eliminate reverse current in LLC topologies. The wide input voltage range accommodates various bus configurations. Consider the SOIC-8 footprint for space-constrained designs. Evaluate the 175µA sleep current for strict energy efficiency standards in consumer electronics.

Power Supply Controllers, Monitors Part Context

This device belongs to the MP6924 family of intelligent rectifiers from Monolithic Power Systems. It complements primary-side controllers like the HR1211 in multi-port charging solutions. The series focuses on reducing external component count while enhancing system reliability through integrated protection features and optimized switching performance.

Power Supply Controllers, Monitors Replacement Considerations

MP6924AGS-P and MP6924AGS-Z are direct equivalents differing only in packaging format. MP6924GS variants offer similar functionality but may have distinct forward voltage characteristics. Verify pinout and thermal performance before substituting with other synchronous rectifier ICs.
