Overview
The EL1848IYZ-T13 is a DC-DC step-up LED driver IC manufactured by Renesas Electronics Corporation. It features a single output capable of regulating up to 400mA for LED applications. The device operates within an input voltage range of 2.6V to 13.2V and supports output voltages up to 14V. It integrates a 1MHz switching frequency regulator suitable for backlighting systems. The component is housed in an 8-MSOP surface-mount package and functions across a temperature range of -40°C to 85°C.
Feature Summary
- Integrates a DC-DC boost converter for efficient LED power regulation
- Supports dimming control capabilities for display backlighting
- Includes internal switching elements to minimize external component count
Applications
- LED backlight drivers for portable electronic devices
- White LED step-up regulation circuits
- Display illumination systems requiring compact power management
Procurement Notes
Verify the current product status, as this specific part number may be obsolete or discontinued. Confirm that the 8-MSOP package variant matches your PCB footprint requirements. Ensure compatibility with the specified 2.6V to 13.2V input range for your target application design.
Selection Notes
Select this component when a compact solution for driving white LEDs from low-voltage sources is required. The integrated boost topology simplifies design compared to discrete solutions. Consider the 400mA current limit and 1MHz frequency when evaluating thermal performance and inductor selection for the final circuit.
Part Context
This part belongs to the EL1848 family of LED drivers from Renesas. Similar variants include the EL1848IWTZ-T7, which utilizes a TSOT-23-8 package instead of MSOP. The family focuses on providing regulated current for LED backlighting in mobile and consumer electronics applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify if other members of the EL1848 series or compatible Renesas LED drivers meet the electrical and packaging requirements.
