Overview
The EL1848IWT-T7A is a regulated LED driver manufactured by Renesas Electronics Corporation. It integrates a boost DC-DC converter designed for driving LEDs, specifically targeting backlight applications. The device operates within an input voltage range of 2.6V to 13.2V and supports output voltages up to 14V. It provides a regulated output current of 400mA with a switching frequency of 1MHz. The component is housed in a TSOT-23-8 surface-mount package and functions across a temperature range of -40°C to 85°C.
Feature Summary
- Integrates a boost DC-DC converter topology for efficient LED power regulation
- Provides constant current regulation suitable for backlight illumination systems
Applications
- LED backlighting systems
Procurement Notes
Verify the exact suffix against official Renesas documentation, as the provided model includes a 'T7A' suffix which may differ from the standard 'T7' variant listed in some public catalogs. Confirm end-of-life status and availability through authorized distributors, as discontinuation notices may apply to specific packaging or revision codes.
Selection Notes
Select this component when a compact solution for low-voltage LED backlighting is required. Ensure the design accommodates the 1MHz switching frequency for inductor sizing and the 400mA current limit matches the LED string requirements. Verify that the operating environment stays within the specified -40°C to 85°C ambient temperature range.
Part Context
This part belongs to the EL1848 series of LED drivers from Renesas. It is functionally similar to other variants like the EL1848IWTZ-T7 and EL1848IY-T13, differing primarily in package type (TSOT-23-8 vs MSOP) and reel specifications. These devices are engineered for portable electronics requiring efficient, space-constrained power management for display backlights.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Renesas technical support for cross-reference recommendations if this specific package or suffix is unavailable.
