MAX1821EBC-T

Overview

The MAX1821EBC-T is a high-efficiency synchronous step-down DC-DC converter featuring an integrated power-on reset function. It operates with an input voltage range of 2.6V to 5.5V and provides a single adjustable output voltage ranging from 1.25V to 5.5V. The device achieves up to 95% efficiency, making it suitable for power-sensitive applications. It is housed in a 10-WFBGA package and functions within a temperature range of -40°C to 85°C.

Feature Summary

• High-efficiency synchronous step-down conversion architecture
• Integrated power-on reset generator for system protection
• Adjustable output voltage capability for flexible design

Applications

• DDR voltage regulation
• General-purpose DC-DC converter circuits
• Power management for integrated circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when reviewing official documentation. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated to ensure component authenticity. Cross-reference the 10-WFBGA package type against your board layout requirements. Ensure the operating temperature range meets your environmental specifications before finalizing procurement decisions.

Selection Notes

Select this component when an adjustable output voltage between 1.25V and 5.5V is required from a 2.6V to 5.5V input source. The integrated power-on reset feature simplifies system startup sequences. Consider the 10-WFBGA package size for space-constrained designs. Evaluate the thermal performance within the specified -40°C to 85°C range for your specific application environment.

Part Context

This part belongs to the MAX1821 series of high-efficiency synchronous step-down converters. The series is designed for applications requiring precise voltage regulation and power savings. The MAX1821EBC-T variant specifically offers adjustable output settings, distinguishing it from fixed-voltage alternatives within the same product family.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the MAX1821 series or equivalent synchronous buck converters from other manufacturers. Verify that any replacement maintains the 2.6V to 5.5V input range and 10-WFBGA package compatibility.
