MAX1637EEE+

DC DC Switching Controllers Overview

The MAX1637EEE+ is a miniature, low-voltage, precision step-down DC-DC switching regulator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with an input voltage range of 2.7V to 5.5V and delivers a programmable output voltage from 0.8V to 5.0V. The device integrates a high-side N-channel MOSFET switch capable of delivering up to 1A of continuous load current. It features a fixed 1.2MHz switching frequency and supports external synchronization. The component is housed in a thermally enhanced 10-pin TDFN package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'EEE+' against official datasheets to confirm lead-free status and RoHS compliance. Confirm package dimensions match the 10-pin TDFN specification. Check for obsolescence notices or lifecycle changes directly from Analog Devices documentation before procurement planning.

DC DC Switching Controllers Selection Notes

Select this component when a small footprint and low input voltage operation are required. Ensure the application demands a maximum load current within the 1A limit. Verify that the desired output voltage falls within the 0.8V to 5.0V programmable range defined by the internal feedback network.

DC DC Switching Controllers Part Context

This part belongs to the MAX1637 family of synchronous step-down regulators designed for space-constrained applications. It utilizes a fixed-frequency current-mode architecture to maintain stability across varying load conditions. The family targets portable devices requiring efficient power conversion from single-cell lithium-ion sources.

DC DC Switching Controllers Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts support the same 10-pin TDFN package and 1A current capability.
