MAX1821XEBC+

Overview

The MAX1821XEBC+ is a synchronous PWM buck regulator from Analog Devices/Maxim Integrated. It delivers up to 600mA output current with an externally programmable voltage range of 1.25V to 5.5V. The device operates at a fixed switching frequency of 1MHz and supports a supply voltage up to 5.5V. Key protection features include under-voltage lockout and over-current protection.

Feature Summary

• Integrates tailored control architectures for specific load demands
• Provides synchronous step-down regulation for efficient power conversion
• Includes built-in under-voltage lockout and over-current protection

Applications

• Embedded communication systems
• Human-machine interface (HMI) projects
• Display applications with external peripherals

Procurement Notes

Verify the exact package type, as sources indicate variations such as 8-WFBGA or PBGA10. Confirm the manufacturer designation matches Analog Devices Inc./Maxim Integrated. Ensure the part number suffix aligns with your required lead time and availability constraints before ordering.

Selection Notes

Select this component when a compact synchronous buck solution is needed for low-power digital loads. It is suitable for designs requiring a fixed 1MHz frequency to minimize passive component size. Verify that the input voltage does not exceed 5.5V and that the load current remains within the 600mA limit.

Part Context

This device belongs to the Maxim Integrated PMIC portfolio, now part of Analog Devices. It serves as a compact power management solution for portable and embedded electronics. The series focuses on integrating control logic with power switches to reduce board space and improve efficiency in consumer and industrial applications.
