LT1683IG#TRPBF

Overview

The LT1683IG#TRPBF is a slew rate controlled ultralow noise push-pull DC/DC controller designed to minimize conducted and radiated electromagnetic interference. It operates with an input voltage range of 2.55 V to 20 V and supports switching frequencies from 20 kHz to 250 kHz. The device provides a single output capable of 10 mA drive current, utilizing a push-pull topology for positive and negative step-up or step-down applications. It functions within a temperature range of -40°C to +125°C and features clock synchronization, soft start, and shutdown capabilities.

Feature Summary

Slew rate control mechanism reduces electromagnetic interference emissions
Ultralow noise architecture for sensitive power applications
Clock synchronization capability for frequency alignment
Integrated soft start and shutdown control functions

Applications

Low noise power supplies for audio equipment
Sensitive analog circuit power management
EMI-constrained industrial systems
Portable devices requiring efficient DC-DC conversion

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and manufacturing origin against the latest datasheet specifications. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly. Cross-reference ordering part numbers to distinguish between tube and reel packaging variants. Validate supplier documentation matches the specific LT1683IG#TRPBF designation.

Selection Notes

Select this controller when minimizing EMI is critical for system compliance. Consider the 20-SSOP package constraints for PCB layout efficiency. Evaluate the 20 kHz to 250 kHz frequency range against transformer size requirements. Assess the 2.55 V to 20 V input range compatibility with source voltages. Verify that the 10 mA output current meets gate drive demands for external switches.

Part Context

The LT1683 belongs to Analog Devices' family of switching regulator controllers focused on low noise performance. It serves as a specialized solution for applications where standard controllers generate excessive electromagnetic interference. The IG suffix indicates the specific temperature grade and package configuration. This component bridges the gap between high-frequency efficiency and strict emission limits.
