LM3538TME/NOPB

LED Driver IC Overview

The LM3538TME/NOPB is a six-channel white LED driver IC designed for backlight applications. It integrates four low-dropout regulators (LDOs) to power external components. The device supports I2C and PWM control interfaces for brightness adjustment. It operates within an ambient temperature range of -30°C to +85°C. Key electrical specifications include a maximum operating temperature of +110°C, a drive current capability of 25mA per channel, and operation via a switched-capacitor charge pump topology.

LED Driver IC Procurement Notes

Verify the specific suffix 'TME' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements as indicated by the 'NOPB' designation. Cross-reference the datasheet revision date with your project timeline to account for potential manufacturing changes or lifecycle status updates.

LED Driver IC Selection Notes

Select this component when a compact solution for multi-channel WLED driving is required. The integrated LDOs reduce external bill of materials compared to discrete solutions. Consider the I2C interface requirement for system architecture compatibility. Evaluate the 25mA output current limit against the specific LED string requirements of the target application design.

LED Driver IC Part Context

This part belongs to the Texas Instruments LM3533/LM3538 family of LED lighting drivers. It is specifically engineered for white LED backlighting in portable devices. The 'NOPB' suffix indicates lead-free construction and absence of certain prohibited substances. It serves as a specialized power management IC within the broader PMIC category.

LED Driver IC Replacement Considerations

Consult the official datasheet for direct pin-to-pin compatible alternatives within the LM353x series. Verify if the LM3533 variant meets the specific channel count and integration needs of the design.
