LT3582EUD-5#TRPBF

Overview

The LT3582EUD-5#TRPBF is a dual-channel DC/DC converter manufactured by Analog Devices Inc., housed in a 16-pin QFN package. It integrates a boost converter and an inverting buck-boost converter driven by a single external inductor. The device provides two regulated outputs: a positive output of 5 V with a maximum current of 200 mA, and a negative output generated via the inverting topology. It operates from an input voltage range of 2.475 V to 5.5 V. Key electrical parameters include a switching frequency of 100 kHz and a quiescent current of 325 uA. The component supports a shutdown function and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrates boost and inverting topologies using a single external inductor for space-efficient design
Provides simultaneous positive and negative regulated outputs suitable for biasing applications
Includes a shutdown pin for power management control

Applications

Active matrix OLED display bias circuits
CCD (Charge-Coupled Device) application power supplies
Systems requiring combined positive and negative voltage rails

Procurement Notes

Verify the specific suffix against official documentation to confirm the tape-and-reel packaging designation. Confirm that the -5 variant matches the required 5V output specification for your circuit design. Ensure compatibility with the 16-QFN footprint during PCB layout. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or thermal requirements.

Selection Notes

Select this component when a compact solution is needed to generate both positive and negative voltages from a single inductor. It is appropriate for designs where input voltages range between 2.475 V and 5.5 V. Consider the 200 mA output current limit and the 100 kHz switching frequency when designing passive components. Verify that the thermal performance of the QFN package meets the system's dissipation needs.

Part Context

This part belongs to the LT3582 family of dual-channel DC/DC converters. The family includes variants such as LT3582EUD-12#PBF, which offers a different fixed output voltage. These devices are designed to simplify power supply design for applications requiring multiple polarity outputs without the complexity of multiple inductors.
