MP1529DR-LF-Z

LED Driver IC Overview

The MP1529DR-LF-Z is an LED lighting driver IC from Monolithic Power Systems, designed for LCD backlight and camera flash applications. It features a boost topology with three outputs: two channels for backlight (2x6) and one for flash (1x4). The device operates on a 2.7 V to 5.5 V input supply, delivering up to 25 V output voltage. It functions at a switching frequency of 1.2 MHz within a -40°C to +85°C temperature range. Packaged in a QFN-16 form factor, it supports PWM dimming for precise control.

LED Driver IC Feature Summary

• Integrates dual backlight channels and a dedicated high-current flash channel for mobile imaging systems
• Supports PWM dimming for accurate brightness regulation across operating conditions
• Utilizes synchronous boost conversion for efficient power management in portable devices

LED Driver IC Applications

• LCD backlight driving for mobile phones and tablets
• Camera flash illumination for smartphones and digital cameras
• White LED driver circuits in portable consumer electronics

LED Driver IC Procurement Notes

Verify the component status as NRND (Not Recommended for New Designs), indicating it may be obsolete or phased out. Confirm RoHS compliance details through official datasheets. Ensure compatibility with existing PCB footprints and design constraints before procurement, as availability may be limited due to end-of-life status.

LED Driver IC Selection Notes

Select this component for designs requiring integrated backlight and flash control in a compact QFN-16 package. Consider its 1.2 MHz switching frequency for EMI management and efficiency trade-offs. Evaluate thermal performance within the specified -40°C to +85°C range. Verify that the 2.7 V to 5.5 V input range aligns with the system's battery or power supply architecture.

LED Driver IC Part Context

Part of the MP1529 series from Monolithic Power Systems, focusing on LED driver solutions. The DR suffix indicates tape-and-reel packaging, while LF-Z denotes lead-free and halogen-free construction. This specific variant targets mobile multimedia applications requiring synchronized backlight and flash functionality.

LED Driver IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components should be evaluated based on functional equivalence, pin compatibility, and electrical specifications rather than direct cross-reference lists.
