LED Driver IC datasheet and documents for LM3502ITL-44/NOPB

LM3502ITL-44/NOPB

LED Driver IC Overview

The LM3502ITL-44/NOPB is a step-up converter designed for white LED applications. It features an internal switch with a maximum output current of 750mA and supports a supply voltage up to 5.5V. The device generates an output voltage of 44V and operates at a switching frequency of 1MHz. It includes PWM dimming capabilities for brightness control. The component is housed in a 10DSBGA package, suitable for compact lighting designs.

LED Driver IC Feature Summary

Integrated step-up converter architecture optimized for white LED backlighting
Supports PWM dimming for precise analog brightness regulation
Internal high-current switch capable of driving LED loads efficiently

LED Driver IC Applications

Dual-display constant current LED driver systems
Large single white LED string backlighting solutions
General-purpose white LED lighting applications requiring regulated current

LED Driver IC Procurement Notes

Verify the specific suffix ITL-44/NOPB against the manufacturer's official documentation to ensure compatibility with required operating temperatures and packaging standards. Confirm that the 10DSBGA package dimensions align with your PCB layout constraints. Cross-reference the datasheet revision history to validate electrical characteristics such as the 1MHz switching frequency and 44V output capability before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when designing circuits for dual-display or large single-string white LED backlights. Ensure the input supply voltage remains within the 5.5V maximum limit. Verify that the required LED forward voltage does not exceed the 44V output capability. Consider the 750mA switch current rating to match the target LED load requirements without exceeding thermal limits.

LED Driver IC Part Context

This part belongs to the LM3502 series from Texas Instruments, which provides complete solutions for white LED drivers. It is distinct from other LM35xx variants like the LM350 linear regulator or the LM3503 dual-display driver. The LM3502 specifically addresses step-up conversion needs for LED strings, differentiating it from standard linear regulators or non-isolated DC-DC converters.
