LT3483EDC#TRPBF

Overview

The LT3483EDC#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 a maximum output current of 200 mA at -38 V. The device features a fixed switching frequency of 150 kHz and a typical quiescent current of 40 uA. It supports shutdown functionality and functions as a single-output negative adjustable regulator. The component is housed in an 8-WFDFN package and is rated for operation between -40°C and +125°C.

Feature Summary

Integrates a Schottky diode to minimize external component count
Requires only one resistor for feedback configuration
Supports shutdown mode for power conservation

Applications

Portable instrumentation requiring negative supply rails
Battery-powered systems with space constraints
Industrial control circuits needing isolated negative voltages

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and thermal characteristics. Ensure the ordering part number matches the required package variant. Confirm RoHS compliance status through the manufacturer's latest release notes. Validate that the supplier provides genuine components with traceable origin. Check for any recent lifecycle changes or obsolescence notices directly from the manufacturer.

Selection Notes

Select this component when a compact inverting topology is required for low-power applications. The integrated Schottky diode simplifies layout compared to discrete solutions. Consider the 150 kHz switching frequency for EMI management relative to higher-frequency alternatives. Evaluate the 40 uA quiescent current against system standby requirements. Ensure the 16 V maximum input voltage aligns with the source supply limits.

Part Context

This part belongs to the LT3483 family of micropower inverting converters. It shares core architecture with variants like the LT3483ES6 but differs in package type. The family emphasizes high integration and small footprint for portable electronics. Analog Devices designs these ICs to replace larger discrete inverting solutions.
