LM3532TME-40/NOPB

LED Driver IC Overview

The LM3532TME-40/NOPB is a high-efficiency white LED driver IC from Texas Instruments, designed for portable applications. It operates on a single-cell lithium-ion battery with an input voltage range of 2.7V to 5.5V. The device integrates a boost converter topology to drive up to three LEDs in series, delivering a regulated output current of 30mA. It features PWM dimming control and supports a switching frequency of 500kHz. The component is housed in a compact DSBGA-16 package, suitable for space-constrained designs.

LED Driver IC Feature Summary

• Integrates a high-efficiency boost converter for driving multiple white LEDs from a single cell source
• Supports precise PWM dimming control for brightness adjustment without color shift
• Includes internal compensation and protection features for stable operation

LED Driver IC Applications

• Portable electronic devices requiring backlighting
• Mobile phone camera flash systems
• Handheld gaming consoles and PDA illumination

LED Driver IC Procurement Notes

Verify the specific suffix 'A' against the requested part number, as LM3532TME-40A/NOPB may denote a distinct revision or variant compared to the base model. Confirm the package type matches the required PCB footprint. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability before finalizing orders.

LED Driver IC Selection Notes

Select this component when designing circuits that require driving multiple series-connected white LEDs from a low-voltage single-cell battery. The integrated boost topology eliminates the need for external inductors in some configurations, simplifying the design. Consider the 30mA output current limit and the maximum output voltage capability when determining the number of LEDs in the string.

LED Driver IC Part Context

This device belongs to the LM3530/32 family of LED drivers from Texas Instruments. While sharing similar functional principles, the LM3532 specifically supports three-channel outputs, distinguishing it from single-output variants like the LM3530. It is engineered for high efficiency and small form factor requirements in consumer electronics.
