Procurement Notes

Verify the specific suffix (e.g., +T) for tape-and-reel packaging requirements. Confirm availability status as distribution channels may indicate limited stock or special order conditions. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm pinout and electrical specifications before procurement.

Selection Notes

Select this component when multiple regulated outputs are required from a single controller IC. It is suitable for designs needing low noise performance at 500kHz switching frequency. Consider external MOSFET selection carefully as output current capability depends on these discrete components. Verify that the input voltage range of 4.2V to 30V aligns with the system power rail.

Part Context

This part belongs to the Maxim Integrated power management portfolio, specifically focusing on multi-output regulators. It complements other solutions like Silent Switcher and µModule products by providing flexible, low-noise power sequencing. The device integrates control logic while relying on external power stages for high-current delivery.

Replacement Considerations

Check for direct substitutes within the MAX1901 family or compatible multi-output controllers from Analog Devices. Ensure replacement parts support the same 500kHz frequency and input voltage range. Verify pin compatibility if footprint constraints exist.
