LT3483EDC

Overview

The LT3483EDC 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 maximum output current of 200 mA. The device features a fixed switching frequency of 150 kHz and maintains a quiescent current of 40 uA. It supports an output voltage of -38 V and functions within a temperature range of -40 C to +85 C. The component utilizes a TSOT-23-6 surface-mount package for compact integration.

Feature Summary

Inverts input voltage to generate negative output rails
Integrates internal Schottky diode for efficiency
Maintains low quiescent current for battery operation

Applications

Portable instrumentation requiring negative supply rails
Battery-powered systems needing efficient voltage inversion
Industrial control modules with limited power budgets

Procurement Notes

Verify the specific suffix and tape/reel configuration against the manufacturer's official ordering guide. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the part number matches the exact thermal grade and packaging requirements for your assembly process.

Selection Notes

Select this component when a negative voltage rail is required from a single positive source. Consider the 200 mA output limit and 150 kHz switching frequency for filter design. Evaluate the TSOT-23-6 footprint constraints and thermal performance relative to your PCB layout capabilities.

Part Context

This part belongs to the LT3483 series of micropower converters. It is designed for applications requiring small form factors and high efficiency. The series typically includes variants with different output configurations or pinouts, sharing the core inverting topology and low-power characteristics.
