LT3483IDC#TRPBF

Overview

The LT3483IDC#TRPBF is an inverting micropower DC/DC converter from Analog Devices, housed in an 8-WFDFN package. It operates with an input voltage range of 2.5 V to 16 V and provides a single adjustable output up to -38 V at 200 mA. The device features a 150 kHz switching frequency and a quiescent current of 40 uA. It includes an internal 40V Schottky diode and power switch, supporting shutdown functionality within a -40°C to +85°C temperature range.

Feature Summary

Integrates an internal 40V Schottky diode and power switch for compact design
Requires only one external resistor for feedback configuration
Supports shutdown mode for extended battery life

Applications

Portable instrumentation requiring negative supply rails
Battery-powered systems needing low quiescent current
Industrial control circuits with space constraints

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the operating temperature grade matches application requirements. Check current availability status as distribution may vary. Ensure the 8-WFDFN footprint aligns with PCB layout specifications before procurement.

Selection Notes

Select this component for applications requiring a negative voltage rail from a single positive source. The 200mA output current suits moderate load demands. Consider the 150kHz frequency for balancing efficiency and component size. Verify input voltage stability within the 2.5V to 16V range during operation.

Part Context

This part belongs to the LT3483 series of inverting DC/DC converters. It shares functional similarities with other micropower regulators but is distinct in its integrated Schottky diode and specific pinout. The IDC package variant offers surface-mount compatibility for automated assembly processes.
