LT3593EDC#TRMPBF

LED Driver IC Overview

The LT3593EDC#TRMPBF is a step-up DC/DC converter designed to drive up to ten white LEDs in series from a single Li-Ion cell. It operates with an input voltage range of 2.7V to 5.5V and provides a regulated output current of 45mA. The device integrates a 1MHz switching frequency, internal power switch, and dimming control capabilities. It is housed in a compact 6-DFN (2x2mm) package and functions within a junction temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Integrated step-up DC/DC converter topology for driving multiple series-connected white LEDs
• Built-in dimming control functionality for brightness adjustment
• Compact surface-mount packaging suitable for space-constrained portable designs

LED Driver IC Applications

• Backlighting for mobile devices
• Portable electronic equipment illumination
• Single-cell lithium-ion powered LED systems

LED Driver IC Procurement Notes

Verify the specific suffix TRMPBF indicates tape-and-reel packaging with moisture sensitivity level 1. Confirm the DFN-6 package dimensions match your PCB footprint requirements. Ensure the 45mA output current aligns with your LED string configuration. Check RoHS compliance status for your region's regulatory needs before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a boost converter is required to drive high-voltage LED strings from low-voltage sources like single-cell batteries. The integrated switch eliminates external inductor losses associated with discrete solutions. Consider the 1MHz frequency for smaller passive components compared to lower-frequency alternatives. Verify that the 45mA constant current rating meets the luminance requirements of the target application.

LED Driver IC Part Context

This part belongs to the LT3593 family of LED drivers manufactured by Analog Devices Inc. The family focuses on efficient power conversion for lighting applications using minimal external components. The EDC suffix denotes the specific DFN-6 package variant optimized for thermal performance and board space efficiency.

LED Driver IC Replacement Considerations

LT3593ES6#TRMPBF offers identical electrical specifications but utilizes a TSOT-23-6 package instead of DFN-6. Verify mechanical compatibility if replacing due to footprint constraints.
