MP24895GQ-Z

LED Driver IC Overview

The MP24895GQ-Z is a monolithic step-down DC-DC converter designed for LED lighting applications. It integrates a high-side N-channel MOSFET and operates from an input voltage range of 6V to 36V. The device delivers up to 700mA of output current with a fixed switching frequency of 1MHz. It supports both analog and PWM dimming methods for brightness control. Key protection features include cycle-by-cycle current limiting, thermal shutdown, and short-circuit protection. The component is housed in a compact 6-QFN (3x3mm) package suitable for surface-mount assembly.

LED Driver IC Feature Summary

• Integrates a high-side N-channel power switch for efficient step-down conversion
• Supports dual dimming modes including analog control and pulse-width modulation
• Includes comprehensive protection mechanisms such as thermal shutdown and overcurrent limiting

LED Driver IC Applications

• LED backlighting for displays
• General LED lighting systems
• Automotive indicator controls

LED Driver IC Procurement Notes

Verify the specific suffix GQ-Z against the manufacturer's latest datasheet to confirm pinout and electrical specifications match the design requirements. Ensure the ordering quantity aligns with the standard reel packaging size defined by Monolithic Power Systems. Confirm RoHS compliance status if required by the target market regulations before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a compact solution is needed for driving single-string white LEDs from higher voltage rails. The fixed 1MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 36V maximum input rating and 700mA current limit to ensure adequate headroom for the specific LED load and operating conditions.

LED Driver IC Part Context

This part belongs to the MP24895 family of LED drivers from Monolithic Power Systems. It is functionally similar to the MP24893 but offers different packaging or specific parameter optimizations. The GQ-Z suffix indicates a specific tape-and-reel packaging variant compliant with certain environmental standards. It serves as a dedicated driver for constant current LED applications requiring high efficiency and small footprint.

LED Driver IC Replacement Considerations

The MP24895GQ-P is listed as a parameter-equivalent alternative within the same product line. Verify that the P suffix variant maintains identical electrical characteristics and pin compatibility before substitution.
