MAX17435ETG+

Battery Chargers Overview

The MAX17435ETG+ is a high-efficiency, synchronous step-down DC-DC converter from Analog Devices. It integrates two N-channel power switches and operates with an input voltage range of 2.7V to 5.5V. The device delivers up to 3A output current with a switching frequency selectable at 1MHz or 2.2MHz. Key features include integrated compensation, programmable soft-start, and comprehensive protection mechanisms such as over-current, over-voltage, and thermal shutdown. It is housed in a compact 6-lead TDFN package.

Battery Chargers Feature Summary

• Integrated synchronous rectification for high efficiency
• Fixed internal compensation simplifies design
• Selectable switching frequencies optimize size and performance
• Comprehensive protection against faults and overheating

Battery Chargers Applications

• Portable electronics and mobile devices
• Industrial control systems
• Infotainment and display drivers

Battery Chargers Procurement Notes

Verify the suffix 'ETG+' indicates the lead-free (RoHS compliant) variant in the TDFN package. Confirm the manufacturer designation is Analog Devices Inc., as Maxim Integrated products are now part of ADI. Ensure the ordering part number matches the specific pinout and thermal pad requirements for your PCB layout.

Battery Chargers Selection Notes

Select this component when a compact solution is required for 3.3V or 5V rail generation from a single-cell lithium battery or USB source. The fixed compensation reduces external component count compared to adjustable regulators. Consider the 2.2MHz option if minimizing inductor size is critical, while the 1MHz option may offer slightly better light-load efficiency.

Battery Chargers Part Context

This device belongs to the MAX174xx family of synchronous buck converters. It serves as a direct replacement for older linear regulators in low-voltage applications where heat dissipation is a concern. The integration of power switches eliminates the need for external Schottky diodes, improving reliability and reducing board space.

Battery Chargers Replacement Considerations

Compatible substitutes include the MAX17430 and MAX17431, which share similar electrical characteristics but may differ in maximum output current or package options. Verify that any alternative maintains the same input voltage range and switching frequency options to ensure circuit compatibility.
