MP24895-AGH

LED Driver IC Overview

The MP24895-AGH is a step-down white LED driver IC from Monolithic Power Systems, designed for driving high-brightness LEDs. It operates with a wide input voltage range of 6V to 36V and supports an output current of up to 1A. The device utilizes a hysteretic control scheme for optimal loop stabilization and quick response times. Key electrical parameters include a low 100mV average feedback voltage to reduce power loss, PWM dimming resolution of 1000:1, and an operating frequency range of 200 kHz to 600 kHz. It features internal UVLO and thermal shutdown protection.

LED Driver IC Feature Summary

• Employs hysteretic control scheme for rapid response and stable regulation
• Supports combined PWM and analog dimming via the EN/DIM pin
• Integrates internal under-voltage lockout and thermal overload protection

LED Driver IC Applications

• Driving WLED arrays for LCD panels in virtual reality displays
• General LED lighting applications requiring wide input voltage tolerance
• Backlighting systems for automotive or industrial displays

LED Driver IC Procurement Notes

Verify the specific suffix (e.g., -AGH) against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure compatibility with system input voltages within the 6V to 36V range. Confirm that the required dimming method aligns with the EN/DIM pin functionality. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

LED Driver IC Selection Notes

Select this component when a buck topology is required for high-efficiency LED driving from variable input sources. The hysteretic control offers advantages over fixed-frequency PWM controllers in transient response scenarios. Consider the 100mV sense resistor requirement for current setting accuracy. Evaluate thermal management needs based on the 1A output capability and ambient operating conditions.

LED Driver IC Part Context

The MP24895 belongs to MPS's family of single-output LED drivers optimized for efficiency and compact design. It integrates a high-side switch and control logic into a small footprint. The series is characterized by its ability to handle wide input ranges while maintaining precise current regulation through external sensing.

LED Driver IC Replacement Considerations

MP24895GJ-P and MP24895GQ-Z are documented parameter-equivalent alternatives within the same product line. Verify package compatibility (TSOT-23-5 vs QFN-6) and ensure functional equivalence regarding dimming control and protection features before substitution.
