MP1528DQ-LF-Z

LED Driver IC Overview

The MP1528DQ-LF-Z is a boost converter LED driver IC from Monolithic Power Systems, designed for driving white LED arrays. It operates with an input voltage range of 2.7 V to 36 V and supports up to six series-connected LEDs. The device features a 950 mA switch current capability and utilizes analog and PWM dimming for brightness control. Packaged in a compact 6-pin QFN (3x3 mm) format, it integrates protection mechanisms including open-load shutdown and thermal regulation.

LED Driver IC Feature Summary

• Integrates a high-efficiency power MOSFET for low conduction losses
• Supports both analog and digital PWM dimming methods
• Includes open-load protection to prevent damage during LED failure

LED Driver IC Applications

• Virtual reality LCD panel backlighting
• White LED array drivers for portable electronics
• Single-cell lithium-ion battery powered lighting systems

LED Driver IC Procurement Notes

Verify the specific package variant, as the MP1528 family includes MSOP-8 and QFN-6 options. Confirm RoHS compliance status through official manufacturer documentation. Ensure the selected part matches the required thermal performance for the intended enclosure. Cross-reference the datasheet revision date to confirm feature consistency.

LED Driver IC Selection Notes

Select this component when a single-cell lithium-ion source drives multiple series LEDs. The boost topology is suitable for applications requiring output voltages exceeding the input supply. Consider the QFN-6 package for space-constrained designs. Evaluate the need for PWM dimming interfaces in the system architecture before finalizing the design.

LED Driver IC Part Context

This part belongs to the MP1528 series of LED lighting drivers. The 'DQ' suffix indicates the 6-pin QFN package type, while 'LF' denotes lead-free construction. The 'Z' suffix typically signifies tape and reel packaging. This series is engineered for high efficiency and minimal external component count in portable display backlighting.

LED Driver IC Replacement Considerations

MP1528DQ-LF-P is the same electrical specification but in tube packaging. MP1528DK-LF-Z offers the same function in an MSOP-8 package. Verify pinout compatibility and thermal pad requirements when substituting between package types.
