MP3397ES-LF-P

Overview

The MP3397ES-LF-P is a step-up white LED driver IC from Monolithic Power Systems, designed for up to four LED strings with a maximum current of 350mA per string. It operates on a boost topology with an input voltage range of 5V to 28V and a fixed switching frequency of 540kHz. The device supports PWM dimming and is housed in a SOIC-16 package. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Supports up to four independent LED strings with individual current regulation
• Integrates a high-efficiency boost converter for wide input voltage operation
• Enables precise brightness control through pulse-width modulation dimming

Applications

• Backlighting systems for mobile devices and portable electronics
• General illumination circuits requiring multi-string LED arrays
• Automotive interior lighting applications

Procurement Notes

Verify the specific suffix designation carefully during procurement. The provided model includes the 'P' suffix, which may indicate a tape-and-reel packaging configuration distinct from other variants like the 'Z'. Confirm that this specific package type aligns with your assembly requirements before ordering.

Selection Notes

Select this component when designing circuits requiring up to four LED strings driven by a single controller. Ensure the application demands a fixed 540kHz switching frequency and accommodates the specified 5V to 28V input range. Verify that the thermal performance of the SOIC-16 package meets the system's power dissipation needs under maximum load conditions.

Part Context
