LM36272YFFR

LED Driver IC Overview

The LM36272YFFR is a dual-channel LCD backlight and bias power supply from Texas Instruments. It operates with a 5V input and provides two boost outputs up to 30V. The device integrates an internal switch and supports a switching frequency of 1.05MHz. It features adjustable switch frequency, content-adaptive brightness control (CABC), direct PWM dimming, and I2C control. Protection includes overvoltage protection (OVP) and thermal shutdown. The component is housed in a 24-DSBGA package and functions within a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Dual-channel boost topology for simultaneous backlight and bias generation

LED Driver IC Procurement Notes

Verify the specific suffix YFFR against the manufacturer datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the 24-DSBGA configuration. Confirm that the design accounts for the specified operating temperature range and electrical parameters defined in the official documentation.

LED Driver IC Selection Notes

Select this component when a compact solution for dual-channel LED driving is required. It is suitable for applications needing integrated CABC functionality and digital control via I2C. Consider the 24-DSBGA package size constraints and the 1.05MHz switching frequency requirements for inductor selection.

LED Driver IC Part Context

This part belongs to the LM36272 series of LED drivers designed for mobile displays. It replaces older discrete solutions by integrating multiple boost channels and control logic into a single small form factor. The series focuses on efficiency and space savings for portable electronics.

LED Driver IC Replacement Considerations

Check for pin-compatible alternatives within the same family or newer revisions. Verify if updated versions offer improved efficiency or additional protection features while maintaining the same package outline.
