LM3565TLE/NOPB

LED Driver IC Overview

The LM3565TLE/NOPB is a high-current flash LED driver featuring a fixed-frequency synchronous boost converter topology. It operates within an input voltage range of 2.5 V to 5.5 V and supports PWM dimming control. The device delivers up to 930 mA output current for flash applications. It functions at a switching frequency of 4 MHz and includes integrated LED thermal monitoring. The component is housed in a compact 16-DSBGA package with dimensions of 2.5x2.12 mm, suitable for space-constrained mobile designs.

LED Driver IC Feature Summary

• Integrates a synchronous boost converter for high-efficiency power conversion
• Includes built-in LED thermal monitor for safety protection
• Supports PWM dimming for precise brightness control

LED Driver IC Applications

• Camera flash LED drivers
• Mobile device illumination systems
• High-current LED lighting applications

LED Driver IC Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the 'LE' designation matches the required 16-DSBGA package variant. Ensure the ordering part number aligns with the intended reel or cut tape packaging format specified by the distributor. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

LED Driver IC Selection Notes

Select this component when a fixed 4 MHz switching frequency is required to minimize external passive component size. Choose the LM3565 over variants like the LM3560 if higher peak current capability near 930 mA is necessary for flash applications. Consider the 16-DSBGA footprint constraints during PCB layout. Verify that the system input voltage remains within the 2.5 V to 5.5 V operational window for stable regulation.

LED Driver IC Part Context

This device belongs to the LM3565 series of LED lighting drivers from Texas Instruments. It is distinct from the LM3560, which offers different current ratings and I2C interfaces. The LM3565 focuses on high-current flash performance using PWM control rather than digital interface dimming. It serves as a specialized solution for portable electronics requiring reliable flash illumination.
