LT3483AIDC#TRMPBF

Overview

The LT3483AIDC#TRMPBF is an inverting micropower DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5 V to 16 V and delivers a negative output voltage up to -38 V at a maximum current of 200 mA. The device features a low quiescent current of 40 µA and a fixed switching frequency of 150 kHz. It is housed in a compact DFN-8 (3x2 mm) package and supports operation temperatures from -40°C to +85°C.

Feature Summary

Integrates a Schottky diode for efficient inverting topology
Provides micropower operation with low standby current consumption
Supports shutdown mode for extended battery life

Applications

Portable instrumentation requiring negative bias rails
Battery-powered sensor systems
Communication equipment with single-supply constraints

Procurement Notes

Verify the specific suffix IDC against official Analog Devices documentation to confirm the DFN-8 package variant and industrial temperature rating. Ensure compatibility with required PCB footprint dimensions for the 3x2 mm outline. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution for generating negative voltages from a positive source is required. The integrated Schottky diode reduces external component count compared to standard inverting converters. Verify that the 200 mA output current meets the load requirements, as higher currents may necessitate thermal consideration or alternative packages.

Part Context

This part belongs to the LT3483 family of micropower DC/DC converters designed for space-constrained applications. It serves as a specialized power management IC within Analog Devices' portfolio, focusing on efficiency and size reduction for portable electronics where traditional inductors and diodes would consume excessive board area.
