MIC2873YCS-TR

LED Driver IC Overview

The MIC2873YCS-TR is a single-output DC-DC step-up (boost) regulator manufactured by Microchip Technology. It integrates an internal switch and supports single-wire dimming control, delivering a regulated output current of 1.2A suitable for camera flash applications. The device operates within a wide input voltage range and features a compact 9-WLCSP package measuring 1.3x1.3 mm. Designed for high efficiency in portable electronics, it includes protection features such as over-current and thermal shutdown to ensure reliable operation under varying load conditions.

LED Driver IC Feature Summary

• Integrates a high-efficiency synchronous boost converter with a single internal power switch
• Supports single-wire dimming interface for simplified control architecture
• Provides regulated 1.2A output current optimized for LED flash drivers
• Includes comprehensive protection mechanisms against over-current and thermal overload

LED Driver IC Applications

• Camera flash driver circuits in mobile devices
• Portable electronic systems requiring compact boost regulation
• LED illumination modules with single-wire control requirements

LED Driver IC Procurement Notes

Verify the specific suffix YCS corresponds to the required 9-WLCSP 1.3x1.3mm package configuration. Confirm that the single-wire dimming capability aligns with your system's control interface. Ensure the 1.2A output current meets the peak demand of the target LED array. Check for moisture sensitivity level requirements during storage and handling procedures.

LED Driver IC Selection Notes

Select this component when a small footprint is critical due to its 9-WLCSP packaging. It is appropriate for applications needing precise single-wire dimming control rather than PWM or analog methods. Consider the 1.2A limit when sizing the external inductor and output capacitor. Verify input voltage ranges match the battery or supply rail characteristics of the host device.

LED Driver IC Part Context

This part belongs to Microchip's portfolio of power management integrated circuits designed for portable consumer electronics. It falls under the category of LED drivers and DC-DC regulators, specifically targeting camera subsystems where space and efficiency are paramount constraints.

LED Driver IC Replacement Considerations

No publicly confirmed substitute part numbers are available in the provided documentation. Evaluate alternative boost regulators from the same manufacturer only if they support identical single-wire dimming and package dimensions.
