MP6924GS

Power Supply Controllers, Monitors Overview

The MP6924GS-Z is a dual fast turn-off intelligent rectifier designed for LLC resonant converter synchronous rectification. It drives two N-channel MOSFETs, reducing forward voltage drop to approximately 45mV and turning off MOSFETs before current becomes negative. Operating within a 4.2V to 35V VDD range, it supports CCM, CrCM, and DCM modes with a total turn-off delay of 35ns. The device features a shutdown function and low sleep mode current of 175µA. Packaged in an SOIC-8, it operates between -40°C and +125°C with a supply current of 16mA.

Power Supply Controllers, Monitors Procurement Notes

Verify the suffix Z indicates RoHS compliance when sourcing. Confirm the SOIC-8 package dimensions match PCB footprint requirements. Check moisture sensitivity level handling instructions during assembly. Ensure the design accounts for the specific turn-off delay characteristics for LLC topology stability. Validate that the 16mA supply current fits the system's power budget constraints.

Power Supply Controllers, Monitors Selection Notes

Select this component for LLC resonant topologies requiring high efficiency and low standby power. The dual output configuration allows control of two synchronous rectifiers simultaneously. Consider the 35ns turn-off delay for high-frequency operation compatibility. The wide VDD range provides flexibility in auxiliary winding design. Compare against MP6924AGS-Z if improved noise immunity or lower forward voltage regulation is required.
