MP9989GS-Z

OR Controllers, Ideal Diodes Overview

The MP9989GS-Z is a switching controller designed for CCM/DCM Flyback topologies, featuring an integrated ideal diode with a built-in 100V/10mΩ N-channel MOSFET. It operates within a supply voltage range of 4.5 V to 13 V and draws 4 mA of operating current. The device supports a fixed switching frequency of 100 kHz and delivers a maximum output voltage of 13 V. It functions reliably across a temperature range of -40°C to +125°C TJ. Packaged in an 8-SOIC surface-mount format, it ensures non-isolated intelligent rectification.

OR Controllers, Ideal Diodes Feature Summary

• Integrates a high-voltage ideal diode with a low on-resistance internal MOSFET to minimize conduction losses.
• Supports both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) flyback operations.
• Features fast turn-on and turn-off delays for efficient high-frequency switching control.

OR Controllers, Ideal Diodes Applications

• Flyback power supply designs requiring integrated synchronous rectification
• Non-isolated intelligent rectifier circuits
• General-purpose power management IC applications

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance status as per manufacturer declarations. Confirm the SOIC-8 package dimensions match PCB footprint requirements. Check moisture sensitivity level (MSL 2) handling procedures during assembly. Ensure the 100V drain-source voltage rating exceeds peak reflected voltages in the target flyback topology.

OR Controllers, Ideal Diodes Selection Notes

Select this component when a compact solution combining flyback control and synchronous rectification is required. The integrated MOSFET eliminates external diode selection, reducing bill of materials. Verify that the 100V voltage rating accommodates the transformer's secondary peak voltage. Consider the 8-SOIC package for thermal dissipation needs relative to QFN alternatives.

OR Controllers, Ideal Diodes Part Context

Part of the MP9989 series from Monolithic Power Systems, focusing on intelligent rectifiers. This series targets efficiency improvements in flyback converters by replacing traditional Schottky diodes with active synchronous rectification controlled internally.
