Overview
The MX841BE is a fixed-frequency, constant current source step-up DC/DC converter designed for LED driving applications. Manufactured by IXYS Integrated Circuits Division, this integrated circuit regulates output current directly to ensure stable LED performance. It operates within an ambient temperature range of -40°C to +85°C and supports a switching frequency of 1MHz. The device delivers a maximum switch current of 2A and provides a voltage output capability of 20V. It is housed in an 8-SOIC surface-mount package with a width of 3.90mm, facilitating compact PCB layouts for backlight and general LED driver systems.
Feature Summary
- Fixed-frequency constant current regulation for direct output current control
- Step-up DC/DC converter topology optimized for LED loads
- Integrated 2A switch capability for high-current LED driving
Applications
- LED backlighting systems
- Constant current LED driver circuits
- Step-up power conversion for lighting modules
Procurement Notes
Verify the complete part number including the suffix BE against official IXYS documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements and thermal management needs for the 8-SOIC form factor. Cross-reference datasheet specifications for electrical limits before integration.
Selection Notes
Select this component for designs requiring a simple, fixed-frequency boost converter for LED strings. Consider the 2A current limit and 20V output capability when sizing the LED array. The 1MHz frequency allows for smaller external passive components compared to lower-frequency alternatives.
Part Context
The MX841 series belongs to IXYS' portfolio of power management ICs focused on LED illumination. This specific model integrates the controller and power switch into a single package, reducing component count and board space. It is part of the broader category of DC/DC regulators tailored for lighting applications.
Replacement Considerations
Check for pin-compatible alternatives from IXYS or other manufacturers offering similar boost LED driver architectures. Verify that substitute parts match the 2A current rating, 1MHz frequency, and 8-SOIC package dimensions to ensure mechanical and electrical interchangeability.
