MP6901DS-LF

Power Supply Controllers, Monitors Overview

The MP6901DS-LF-Z is a flyback switching controller designed as a fast-off intelligent rectifier driver. It operates within an input voltage range of 8 V to 24 V and supports a maximum switching frequency of 400 kHz. The device functions in non-isolated configurations with one output and draws 8 mA of operating supply current. It is rated for an extended temperature range from -40°C to +125°C and utilizes an SOIC-8 surface-mount package.

Power Supply Controllers, Monitors Feature Summary

• Replaces Schottky diodes in flyback converters by regulating external MOSFET forward voltage drop
• Provides rapid turn-off capability to minimize reverse recovery losses
• Supports standard and logic level MOSFET integration

Power Supply Controllers, Monitors Applications

• Flyback power supply designs
• Secondary side synchronous rectification
• High-efficiency AC/DC adapters

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix against official MPS documentation, as variations such as LF-Z indicate lead-free status and tape-and-reel packaging. Confirm that the DS suffix corresponds to the SOIC-8 package type required for your layout. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to assembly processing.

Power Supply Controllers, Monitors Selection Notes

Select this component when designing flyback topologies requiring secondary-side synchronization. It is suitable for applications needing low standby power consumption and high efficiency across DCM and QR modes. Verify compatibility with available external MOSFETs and ensure the 8V to 24V supply range matches the control circuit requirements.
