LT3483EDC#TRMPBF

Overview

The LT3483EDC#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. The device supports an output current of 200 mA while maintaining a low quiescent current of 40 uA. It functions at a fixed switching frequency of 150 kHz and includes internal Schottky rectification. The component is housed in a TSOT-23-6 package and is rated for operation between -40°C and +85°C.

Feature Summary

Inverting topology with integrated Schottky rectifier
Micropower operation with low static current consumption
Fixed 150 kHz switching frequency for compact external components

Applications

Battery-powered systems requiring negative rail generation
Portable instrumentation circuits
Sensor biasing applications

Procurement Notes

Verify the specific suffix TRMPBF indicates tape and reel packaging when sourcing. Confirm the DFN-6 package variant matches the design requirements, as datasheets may list multiple package options for the LT3483 family. Ensure the manufacturer designation remains Analog Devices Inc. or Linear Technology to guarantee original component authenticity.

Selection Notes

Select this component when a negative voltage rail is required from a single positive supply source. The 200 mA output capability suits moderate load currents, while the 40 uA quiescent current preserves battery life in standby modes. The wide input range accommodates various battery chemistries without additional regulation stages.

Part Context

This part belongs to the LT3483 series of inverting DC/DC converters. It is designed for applications where space constraints and power efficiency are critical. The series utilizes a constant frequency current mode architecture to simplify compensation and reduce external component count compared to older inverting topologies.
