Overview
The LM3410XSDX/NOPB is a Texas Instruments LED lighting driver IC designed for boost and SEPIC topologies. It operates with an input voltage range of 2.7 V to 5.5 V and delivers a constant output current up to 2.8 A. The device supports switching frequencies from 1.2 MHz to 2 MHz, enabling the use of small passive components. It provides an adjustable output voltage range of 3 V to 24 V. Packaged in a WSON-6 surface-mount format, it functions within a temperature range of -40°C to +125°C.
Feature Summary
- Supports both boost and SEPIC converter topologies for flexible LED string configurations.
- Integrates PWM dimming capability for precise light intensity control.
- Includes built-in thermal shutdown protection to safeguard against overheating conditions.
Applications
- LED backlighting systems
- Portable electronic device illumination
- General solid-state lighting fixtures
Procurement Notes
Verify that the ordering suffix 'X' denotes the tape-and-reel packaging configuration. Confirm the specific package variant matches the required footprint. Ensure the component meets RoHS compliance standards as indicated by the 'NOPB' designation. Cross-reference the manufacturer part number with official datasheets to validate electrical specifications before integration.
Selection Notes
Select this component when designing circuits requiring high efficiency in compact spaces due to its wide operating frequency range. Choose the LM3410XSDX/NOPB for applications needing robust thermal management and simple external component counts. It is suitable for battery-powered devices where input voltage varies but requires stable LED current regulation.
Part Context
This part belongs to the LM3410 series of LED drivers from Texas Instruments. It shares functional similarities with other variants like the LM3410XMF/NOPB and LM3410XMYX/NOPB, differing primarily in package type and pinout. The series is characterized by its ability to drive LEDs efficiently using minimal external components.
Replacement Considerations
LM3410XMF/NOPB offers identical electrical performance in a SOT-23-5 package. LM3410XMYX/NOPB provides the same functionality in an MSOP-PowerPAD-8 package. Verify pin compatibility and thermal requirements when substituting these alternatives.
