LT3593ES6#TRPBF

LED Driver IC Overview

The LT3593ES6#TRPBF 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 features output disconnect capability. Packaged in a TSOT-23-6 surface-mount case, it supports dimming control and functions within a junction temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Integrates a high-efficiency step-up DC/DC converter topology for driving multiple series-connected white LEDs
• Features one-pin current programming for simplified design and precise output regulation
• Includes output disconnect functionality to eliminate leakage current when the device is disabled

LED Driver IC Applications

• Backlighting for portable electronic devices
• LED illumination driven by single-cell lithium-ion batteries
• General-purpose LED driver circuits requiring compact form factors

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., formerly Linear Technology. Ensure the component meets RoHS3 compliance standards as specified in official documentation. Cross-reference the DigiKey part number LT3593ES6#TRPBFTR-ND for accurate identification during procurement processes.

LED Driver IC Selection Notes

Select this component when designing circuits that require driving up to ten series-connected white LEDs from a low-voltage source. The fixed 1MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. The TSOT-23-6 package is suitable for space-constrained applications. Ensure the input voltage remains within the 2.7V to 5.5V operational range for proper regulation.

LED Driver IC Part Context

The LT3593 belongs to the family of LED driver integrated circuits manufactured by Analog Devices Inc. It is specifically engineered for portable applications where efficiency and size are critical. The ES6 designation refers to the industrial temperature grade and the TSOT-23-6 package type. This part serves as a dedicated solution for constant-current LED driving without requiring complex external feedback networks.
