Voltage Regulators - DC DC Switching Regulators datasheet and documents for MAX638AESA+T

MAX638AESA+T

Voltage Regulators - DC DC Switching Regulators Overview

The MAX638AESA+T is a CMOS step-down switching regulator manufactured by Analog Devices Inc. (Maxim Integrated). It operates with an input voltage range of 2.2V to 16.5V and provides a positive output that is either adjustable or fixed at 1.31V/5V, reaching up to 16.5V maximum. The device features a 65kHz switching frequency and utilizes an 8-SOIC package. It supports surface mount installation and functions within a temperature range of 0°C to 70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Designed for minimum component count in DC-DC conversion applications
Optimized for low power consumption during operation
Integrates synchronous rectification capabilities

Voltage Regulators - DC DC Switching Regulators Applications

Efficient DC-DC step-down regulation
Battery-powered systems requiring low quiescent current
Portable electronic devices

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (+T) indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated to ensure authenticity. Check for RoHS compliance status associated with the + suffix. Ensure the 8-SOIC package dimensions match your PCB footprint requirements before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, low-power buck converter is required for inputs up to 16.5V. Consider the 65kHz switching frequency for trade-offs between component size and efficiency. Verify if the adjustable or fixed output variant meets the specific voltage requirement of the target circuit design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX638 family of step-down switching regulators. It is distinct from the MAX6381-MAX6390 series, which are microprocessor supervisory circuits. The MAX638 focuses on power conversion rather than voltage monitoring or reset generation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The MAX638ACSA+T is a comparable variant within the same family. Verify pin compatibility and output voltage specifications before substitution. Note that lifecycle status may vary between specific suffixes.
