LT3483AIDC#TRPBF

Overview

The LT3483AIDC#TRPBF is a micropower inverting DC/DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 2.5 V to 16 V and delivers up to 200 mA output current at -38 V. The device features a low quiescent current of 40 uA and a fixed switching frequency of 150 kHz. It is housed in an 8-lead DFN package and supports operation from -40°C to +85°C, including shutdown functionality for power management.

Feature Summary

Inverting topology for generating negative voltages from positive sources
Micropower operation with low quiescent current consumption
Integrated Schottky diode for simplified external component count
Shutdown pin for system power control

Applications

Portable instrumentation requiring negative bias rails
Battery-powered systems needing efficient voltage inversion
Industrial sensor interfaces with split supply requirements
Communication equipment utilizing RS-232 or similar transceivers

Procurement Notes

Verify the specific suffix 'A' against official documentation to confirm performance grade variations compared to standard versions. Ensure the DFN-8 package matches PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a compact inverting solution is required for low-power applications. The integrated Schottky diode reduces external part count compared to discrete solutions. Evaluate thermal performance within the DFN-8 package constraints. Consider the 150 kHz switching frequency for EMI sensitivity in sensitive analog circuits.

Part Context

This part belongs to the LT3483 series of micropower DC/DC converters. It is designed for applications where space and power efficiency are critical. The series offers inverting configurations suitable for creating negative supplies from single positive batteries or logic levels.
