Overview
The EL1848IWTZ-T7A is a regulated LED driver manufactured by Renesas Electronics Corporation. It integrates a DC-DC boost converter designed for single-channel LED applications, specifically backlighting. The device supports an input voltage range of 2.6V to 13.2V and delivers a regulated output current of 400mA. It operates with a switching frequency of 1MHz and functions within a temperature range of -40°C to +85°C. The component is housed in a TSOT-23-8 surface-mount package.
Feature Summary
- Integrates a boost converter topology for efficient LED regulation
- Provides constant current output control for backlighting applications
Applications
- LED backlighting systems
Procurement Notes
Verify the specific suffix 'T7A' against official Renesas documentation, as the provided source data lists 'EL1848IWTZ-T7' and 'EL1848IWT-T7'. Confirm if 'T7A' represents a distinct revision or packaging variant. Check product status, as related variants are marked as obsolete. Ensure compatibility with the TSOT-23-8 package requirements.
Selection Notes
Select this component for designs requiring a compact, single-channel LED driver with integrated boost functionality. Consider the 400mA current capability and 1MHz switching frequency for space-constrained backlighting solutions. Verify that the operating temperature range meets the environmental requirements of the target application.
Part Context
This part belongs to the EL1848 series of LED drivers from Renesas Electronics. The series focuses on providing regulated current for LEDs using a boost converter architecture. These components are typically used in portable electronics and displays where efficient power management and small form factors are critical.
Replacement Considerations
Check for direct substitutes within the EL1848 family, such as EL1848IWT-T7 or EL1848IY-T13, ensuring pinout and electrical specifications match. Verify availability as some variants are listed as obsolete.
