Overview
The MAX1856EUB+TG05 is a wide-input-range, synchronizable PWM step-down controller from Analog Devices. It operates with an input voltage range of 3V to 28V and provides a single adjustable output capable of reaching -24V to -72V. Designed for surface-mount installation in 10-uMAX or uSOP packages, it supports operating temperatures from -40°C to +85°C. This device functions as a specialized power management IC suitable for demanding industrial and communication applications.
Feature Summary
- Supports wide input voltage ranges up to 28V
- Features synchronizable PWM operation
- Capable of generating negative output voltages
Applications
- Satellite receiver set-top boxes
- xDSL modems
- Cable modems
Procurement Notes
Verify the specific suffix 'TG05' against official Analog Devices documentation to confirm package and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 10-uMAX/uSOP form factor. Confirm that the negative output capability aligns with system requirements. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement decisions.
Selection Notes
Select this component when designing systems requiring high-voltage input handling and negative rail generation. The synchronizable feature allows integration into multi-phase or clocked environments. Consider the thermal performance within the specified -40°C to +85°C range. Verify that the control loop stability meets the specific load transient requirements of the target application.
Part Context
This part belongs to the MAX1856 series of specialized regulators manufactured by Analog Devices/Maxim Integrated. It is categorized under PMIC (Power Management Integrated Circuits). The device is distinct from standard positive-output LDOs or buck converters due to its ability to handle wide inputs and produce negative outputs, targeting niche communication infrastructure markets.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Generic replacements may not support the specific negative output voltage range or synchronization features required for xDSL and cable modem applications.
