MAX1760HETB+

Overview

The MAX1760HETB+T is a low-noise, step-up DC-DC converter manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 700 mV to 5.5 V and provides an adjustable output voltage from 2.5 V to 5.5 V. The device delivers an output current of 800 mA at a fixed switching frequency of 1 MHz. It features a TDFN-EP-10 package for surface mount installation. The component functions within a temperature range of -40°C to +85°C and includes load regulation of -1.5%. This synchronous boost regulator is designed for efficient power conversion in portable applications.

Feature Summary

• Synchronous boost topology for high efficiency
• Integrated enable pin for power management control

Applications

• Portable consumer electronics
• RF front-end modules
• Battery-powered devices requiring stable voltage rails

Procurement Notes

Verify the exact suffix (e.g., +T) against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status directly with the supplier or manufacturer documentation before procurement. Check for obsolescence notices or limited availability statuses as distribution channels may vary. Ensure the ordering part number matches the specific thermal pad and lead finish requirements defined in the official product specification.

Selection Notes

Select this component when a compact, low-noise boost solution is required for inputs starting below 1 V. The 1 MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Verify that the required output voltage falls within the 2.5 V to 5.5 V range and that the load current does not exceed 800 mA. Consider the TDFN-EP-10 package size constraints and thermal dissipation needs for the specific PCB layout.

Part Context

This part belongs to the MAX1760H series of low-noise, synchronous step-up converters. It is designed to provide clean power for noise-sensitive applications such as wireless communication systems. The series emphasizes small footprint and high efficiency, making it suitable for space-constrained portable designs where battery life and signal integrity are critical priorities.

Replacement Considerations

Consult the official Analog Devices replacement guide for verified cross-reference part numbers. Ensure any substitute maintains the same boost topology, input voltage range, and low-noise characteristics. Verify package compatibility and pinout alignment if direct pin-to-pin replacement is required.
