MAX77711CEWB+T

Overview

The MAX77711CEWB+T is a four-phase, 3A-per-phase configurable step-down regulator designed for 1s/2s lithium-ion battery inputs. It features an I2C-programmable output voltage range from 0.25V to 5.2V with soft-start and soft-stop capabilities. The device integrates a 300mA PMOS LDO and includes six GPIOs for hardware control. It utilizes pseudo-random spread spectrum modulation to suppress electromagnetic interference.

Feature Summary

• Configurable multi-phase architecture supporting single or multiple independent outputs
• Integrated low-dropout linear regulator with active discharge capability
• Spread spectrum modulation technology for enhanced electromagnetic interference reduction

Applications

• DSLR cameras
• HD video mirrorless cameras
• Action cameras
• Portable devices powered by two-cell lithium batteries

Procurement Notes

Verify the specific suffix 'CEWB+T' against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required I2C addressing and GPIO configurations for your target application design.

Selection Notes

Select this component when requiring high current density in a small footprint for portable imaging equipment. Consider the integrated LDO if auxiliary power rails are needed alongside the main buck converter outputs.

Part Context

This part belongs to the MAX77511/MAX77711 family of highly integrated power management solutions. It is specifically engineered for applications demanding efficient power conversion from dual-cell lithium sources while maintaining strict size constraints typical of modern consumer electronics.

Replacement Considerations

The MAX77511CEWB+T serves as a direct functional substitute within the same family, differing primarily by the absence of the integrated PMOS LDO.
