MAX607ESA+T

Overview

The MAX607ESA+T is a low-profile, step-up switching voltage regulator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with an input voltage range of 3 V to 5.5 V and delivers a maximum output current of 180 mA. The device features a fixed switching frequency of 500 kHz and supports multiple output configurations, including fixed 5 V, 12 V, or adjustable outputs ranging from 3 V to 12.5 V. It is housed in an 8-lead SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Boost topology for efficient step-up voltage conversion
• Low-profile surface-mount packaging design
• Fixed internal switching frequency for simplified external component selection

Applications

• Flash memory power supplies
• PCMCIA card voltage conversion
• Battery-powered systems requiring boosted voltage rails

Procurement Notes

Verify the specific suffix and tape/reel configuration when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required output voltage setting, as the family includes both fixed and adjustable options. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when a compact boost converter is needed for single-cell lithium or alkaline battery applications. The 500 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the load current does not exceed the 180 mA limit and that the input voltage remains within the specified 3 V to 5.5 V window for stable operation.

Part Context

This part belongs to the MAX607 series of low-profile switching regulators designed for space-constrained portable electronics. It serves as a power management solution for devices requiring higher voltage rails from low-voltage sources. The series is characterized by its small footprint and ease of implementation in standard SOIC packages.

Replacement Considerations

Check for direct pin-compatible upgrades within the MAX607 family. Verify if newer revisions offer improved efficiency or different output voltage options. Ensure any substitute maintains the same SOIC-8 footprint and thermal characteristics.
