MAX606ESA

Overview

The MAX606ESA is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc. (Maxim Integrated). It operates with an input voltage range of 3 V to 5.5 V and provides adjustable output voltages from 3 V to 12.5 V, alongside fixed 5 V and 12 V options. The device delivers up to 180 mA of output current at a switching frequency of 1 MHz. Packaged in an 8-pin UMAX surface-mount case, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a synchronous rectifier topology for improved efficiency compared to standard boost converters.
• Supports flexible output configurations including fixed 5 V, fixed 12 V, and fully adjustable ranges.
• Utilizes a compact 8-lead UMAX package designed for space-constrained portable applications.

Applications

• Portable battery-powered equipment requiring efficient voltage boosting
• Handheld instruments and measurement devices
• Communication modules operating on single-cell lithium-ion or alkaline batteries

Procurement Notes

Verify the specific suffix 'E' indicates the industrial temperature grade (-40°C to +85°C) distinct from commercial variants. Confirm the 'SA' suffix corresponds to the SOIC-8 package type if cross-referencing with datasheets specifying UMAX-8. Ensure RoHS compliance status matches current manufacturing standards as product lifecycles may shift between active and obsolescence phases.

Selection Notes

Select this component when designing circuits that require high efficiency from low-voltage sources without the size penalty of inductors found in some alternatives. The 1 MHz switching frequency allows for smaller external passive components. Consider the 180 mA current limit against peak load requirements to ensure adequate headroom during transient conditions.

Part Context

This part belongs to the MAX606 series of synchronous step-up converters. It shares functional similarities with other Maxim integrated power solutions but is distinguished by its specific synchronous architecture and UMAX packaging. It serves as a power management IC within the broader PMIC category, targeting portable electronics where size and efficiency are critical constraints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct pin-to-pin replacements only through official manufacturer cross-reference tools.
