Overview
The MP4603ES-LF-P is a current-mode buck-boost white LED driver IC designed for large LCD TV backlight systems. It features an internal switch capable of handling 2.5A output current and operates within a supply voltage range of 5V to 75V. The device functions at an operating frequency of 900 kHz and supports both boost and buck topologies. It is housed in a 16-SOIC package with an operating temperature range from -20°C to +85°C.
Feature Summary
- Integrates a high-current internal switch for efficient power delivery
- Supports flexible buck-boost topology for wide input voltage ranges
- Optimized for driving white LEDs in large display applications
Applications
- Large LCD TV backlight systems (60-inch and larger)
- White LED lighting drivers
- Partial power WLED driver circuits
Procurement Notes
Verify the NRND status, as manufacturers recommend alternative parts for new designs. Confirm the specific suffix requirements for tape and reel packaging. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check for RoHS compliance documentation before finalizing procurement orders.
Selection Notes
Select this component for applications requiring high current drive capabilities up to 2.5A. Consider the 900 kHz switching frequency for balancing efficiency and component size. Evaluate the 5V to 75V input range against system power rails. Ensure the thermal performance of the SOIC-16 package meets the design's heat dissipation requirements.
Part Context
This part belongs to the MP4603 series of LED lighting drivers from Monolithic Power Systems. It serves as a successor or alternative to the MP4601, offering higher current capacity. The series is targeted at professional display backlighting solutions requiring robust buck-boost regulation.
Replacement Considerations
Official recommendations suggest considering the MP4603ES-LF as a direct functional equivalent. Verify pinout compatibility if substituting with other MPS LED drivers. Cross-reference specifications with the MP4601 for lower current requirements.
