MP6908AGJ-P

Overview

The MP6908AGJ-P is a flyback switching controller featuring a fast turn-off intelligent rectifier, designed to replace Schottky diodes in high-efficiency power supplies. It supports DCM, CCM, and quasi-resonant modes with a maximum switching frequency of 400 kHz and a duty cycle limit of 50%. The device operates within a supply voltage range of 4 V to 13 V, delivering up to 12 V output at 3 A current. It functions reliably across an extended temperature range from -40°C to +125°C and utilizes a TSOT23-6 surface-mount package.

Feature Summary

• Eliminates the need for auxiliary windings during secondary-side high-side or low-side rectification
• Integrates programmable ringing detection to prevent false triggering during DCM and quasi-resonant operation
• Provides approximately 30ns fast turn-on and turn-off delays for precise synchronous control

Applications

• High-efficiency flyback converters
• Battery charging applications with low output voltages
• Active clamp flyback topologies

Procurement Notes

Verify that the specific suffix 'P' corresponds to the required tape-and-reel packaging configuration as defined by Monolithic Power Systems. Confirm RoHS compliance status and ensure the TSOT23-6 footprint matches the target PCB design. Cross-reference the datasheet revision to validate electrical characteristics against the intended operating conditions.

Selection Notes

Select this component when designing flyback converters requiring synchronous rectification without auxiliary winding complexity. It is suitable for applications demanding low conduction losses and fast switching speeds. Ensure the external MOSFET selection aligns with the logic-level drive requirements and thermal constraints of the specific power stage.
