MP6902AGJ-Z

Power Supply Controllers, Monitors Overview

The MP6902AGJ-Z is a switching controller designed for flyback topologies, functioning as a fast turn-off intelligent rectifier. It regulates the forward voltage drop of an external MOSFET to approximately 70mV and features a total turn-off delay of 20ns. The device supports a maximum switching frequency of 400kHz and operates with a VDD voltage range of 8V to 24V. It includes a light load mode that reduces static current to 300µA. The component is housed in a TSOT23-6 package and complies with Energy Star 1W standby requirements.

Power Supply Controllers, Monitors Feature Summary

• Regulates external MOSFET forward voltage drop to approximately 70mV for high efficiency
• Provides rapid turn-off capability with a total delay of 20ns to prevent reverse conduction
• Integrates light load management to reduce static current to 300µA during low power operation

Power Supply Controllers, Monitors Applications

• Secondary side synchronous rectification in flyback converters
• High-efficiency AC-DC adapters for notebook computers
• Power supplies supporting DCM and quasi-resonant operating modes

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'Z' indicates lead-free compliance and RoHS status when ordering. Confirm the TSOT23-6 package type matches the PCB footprint design. Ensure the application circuit supports the 8V to 24V VDD input range. Check for moisture sensitivity level requirements during storage and handling procedures.

Power Supply Controllers, Monitors Selection Notes

Select this component for designs requiring precise regulation of synchronous rectifier voltage drops. It is suitable for applications needing fast turn-off speeds to minimize reverse recovery losses. Consider its compatibility with both 12V standard and 5V logic level MOSFETs. Evaluate the need for light load static current reduction for meeting strict standby power standards.
