LT8335EDDB

Overview

The LT8335EDDB is a current mode DC/DC converter from Analog Devices, packaged in an 8-pin DFN. It supports Boost, SEPIC, and Inverting topologies with a single feedback pin for positive or negative output generation. The device features a 2A switch, 28V switch voltage rating, and 2MHz switching frequency. Input voltage ranges from 3V to 25V, with a maximum output of 28V. Quiescent current is 6uA, while shutdown current is 5.5uA. Operating temperature spans -40°C to +125°C.

Feature Summary

Configurable as Boost, SEPIC, or Inverting converter using a single feedback pin
Low quiescent current consumption of 6uA for efficient operation
Integrated 2A synchronous switch with 28V voltage rating
Fixed 2MHz switching frequency for compact external component size

Applications

Generating negative supply rails from positive input sources
Battery-powered systems requiring low standby current
Industrial control circuits needing isolated or inverted voltages
Automotive electronics operating within wide input ranges

Procurement Notes

Verify the specific suffix and tape/reel configuration against the manufacturer's latest datasheet before ordering. Confirm that the DFN-8 package thermal pad connection meets your PCB layout requirements. Ensure the selected variant matches the required temperature grade and switching frequency specifications for your design. Cross-reference the part number with official Analog Devices documentation to avoid counterfeit components.

Selection Notes

Select this component when a flexible topology is needed for generating either positive or negative outputs from a single input source. The low quiescent current makes it suitable for battery-operated applications where standby power is critical. Consider the 2A switch capability and 2MHz frequency for balancing efficiency and component size. Verify input voltage range compatibility with your system's power supply architecture.

Part Context

The LT8335 series includes variants like LT8335IDDB and LT8335EDDB, differing primarily in temperature grade and packaging. These devices are part of Analog Devices' micropower converter lineup, designed for space-constrained applications. The EDDB variant specifically denotes the industrial temperature range and DFN-8 package configuration.
