MAX77711CEWB+T

Special Purpose Regulators 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.

Special Purpose Regulators 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

Special Purpose Regulators Applications

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

Special Purpose Regulators 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.

Special Purpose Regulators 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.

Special Purpose Regulators 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.

Special Purpose Regulators 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.
