MAX1856EUB

Overview

The MAX1856EUB is a series controller and low-dropout regulator IC manufactured by Analog Devices Inc./Maxim Integrated. It features a single output capable of generating voltages ranging from -24V to -72V, powered by an input voltage range of 3V to 28V. The device is housed in a 10-uMAX/uSOP surface-mount package with dimensions of 0.118 inches (3.00mm) width. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated series controller functionality for precise voltage regulation
• Capable of generating negative output voltages down to -72V
• Includes internal monitoring and calibration mechanisms

Applications

• Satellite receiver set-top boxes
• xDSL modem systems
• Cable modem architectures

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix and tape/reel specifications match design requirements. Check current lifecycle status as availability may be restricted. Ensure environmental compliance documentation aligns with project standards.

Selection Notes

Select this component when designing systems requiring stable negative voltage generation from moderate input sources. The compact 10-pin package suits space-constrained PCB layouts. Verify that the required output voltage falls within the specified -24V to -72V range and that operating temperatures remain within the industrial grade limits.

Part Context

This part belongs to the Maxim Integrated PMIC portfolio, specifically designed for communication infrastructure. It integrates control logic with power regulation to simplify system design for broadband access equipment. The uMAX package provides a small footprint compared to traditional SOP variants while maintaining thermal performance.

Replacement Considerations

Consult official substitution lists for pin-compatible alternatives. Verify electrical parameters such as input/output ranges and package dimensions before swapping. Cross-reference datasheets for functional equivalence in satellite and cable modem applications.
