EL1848IWT-T7

Overview

The EL1848IWT-T7 is a regulated LED driver manufactured by Renesas Electronics Corporation. It integrates a DC-DC boost converter designed for driving LEDs, featuring a maximum output current of 400mA and an operating switching frequency of 1MHz. The device supports an input voltage range from 2.6V to 13.2V with a maximum supply voltage of 14V. It is housed in a TSOT-23-8 surface-mount package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-efficiency DC-DC boost converter topology optimized for LED applications
• Provides regulated constant current output capability up to 400mA
• Operates at a fixed 1MHz switching frequency to minimize external component size

Applications

• LED backlighting systems
• General-purpose LED illumination circuits

Procurement Notes

Verify the specific suffix 'T7' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the manufacturer status indicates active production or obsolescence status prior to finalizing design-in decisions, as availability may be subject to change.

Selection Notes

Select this component when a compact solution for low-power LED driving is required. Ensure the application input voltage falls within the specified 2.6V to 13.2V range. Verify that the thermal requirements of the TSOT-23-8 package are compatible with the target PCB layout and ambient operating conditions.
