LM36010YKBR

LED Driver IC Overview

The LM36010YKBR is a high-side LED flash driver IC from Texas Instruments, designed for mobile camera applications. It operates within an input voltage range of 2.5 V to 5.5 V and delivers up to 1.5 A output current. The device utilizes a boost topology with adjustable output voltage and supports switching frequencies of 2 MHz or 4 MHz. It features I2C control interface and overvoltage protection (OVP). Packaged in a DSBGA-8 format, it functions between -40°C and +85°C with a maximum supply current of 300 µA.

LED Driver IC Feature Summary

• Integrated I2C control interface for precise configuration
• Built-in overvoltage protection circuitry
• High-side synchronous boost converter topology

LED Driver IC Applications

• Mobile phone camera flash systems
• Smartphone LED illumination modules
• Portable device camera auxiliary lighting

LED Driver IC Procurement Notes

Verify the specific suffix YKBR against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the target PCB footprint for the DSBGA-8 package. Confirm that the design supports the required I2C addressing and voltage levels for proper integration into the host system.

LED Driver IC Selection Notes

Select this component when a compact, high-current LED driver is needed for mobile photography. The DSBGA-8 package offers space efficiency compared to larger packages. Consider the 2 MHz/4 MHz frequency options based on inductor size constraints and EMI requirements. Verify that the 1.5 A peak current meets the specific LED array demands.

LED Driver IC Part Context

This part belongs to the LM36010 series of SynchBst LED flash drivers. It is distinct from buck converters like the LMR series due to its boost topology. The YKBR suffix indicates a specific packaging variant within the broader LM36010 family, differentiated by physical dimensions and reel specifications rather than internal circuit functionality.

LED Driver IC Replacement Considerations

Consult the official LM36010 datasheet for pin-compatible alternatives within the same series. No direct public substitute part numbers are confirmed in the provided documentation.
