Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix TEEP confirms the 20-pin QSOP package and industrial/extended temperature rating. Confirm RoHS compliance status as lead-free. Ensure the source document explicitly lists the part as active or obsolete, as availability may vary by distributor. Cross-reference pinouts with official Maxim Integrated documentation to avoid interface mismatches.

Power Supply Controllers, Monitors Selection Notes

Select this component when designing power stages for broadband access equipment requiring multiple regulated outputs from a single controller. It is suitable for applications where board space and component count must be minimized. Verify that the input voltage range aligns with the system's unregulated bus voltage. Consider thermal performance within the QSOP package for the intended ambient conditions.

Power Supply Controllers, Monitors Part Context

This part belongs to the MAX1864/MAX1865 family of power-supply controllers developed by Maxim Integrated, now part of Analog Devices Inc. These devices are specifically engineered to simplify the design of multi-rail power systems found in telecommunications infrastructure. The MAX1865 variant provides additional output channels compared to the MAX1864, catering to more complex modem requirements.

Power Supply Controllers, Monitors Replacement Considerations

The MAX1864 is a related model offering fewer outputs. Verify if the reduced channel count meets the application needs. No direct public substitute part numbers are confirmed in the provided data.
