LM3402MRX/J7002927

Overview

The LM3402MRX/J7002927 is a constant current buck regulator designed for driving high-power LEDs. It operates with an input voltage range of 6V to 75V and provides a regulated output current of 500mA. The device supports PWM dimming control and features an adjustable switching frequency from 10kHz to 1MHz. It is housed in an 8-pin SO-PowerPad package and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrated internal power switch eliminates the need for external MOSFETs
Supports high-frequency PWM dimming for precise light intensity control
Constant current regulation ensures stable LED performance across varying conditions

Applications

High-power LED lighting modules
Automotive exterior lighting systems
General illumination applications requiring constant current drive

Procurement Notes

Verify the specific suffix /J7002927 against official Texas Instruments documentation, as this may denote a specific tape-and-reel configuration or customer-specific marking distinct from standard commercial variants. Confirm pinout compatibility and thermal requirements for your PCB layout before finalizing procurement.

Selection Notes

Select this component when a compact solution for driving high-power LEDs is required without external switching transistors. It is suitable for designs needing wide input voltage tolerance and precise current regulation. Ensure the chosen package variant matches the thermal management capabilities of the target application environment.

Part Context

This part belongs to the LM3402 family of LED drivers from Texas Instruments. These devices are engineered specifically for high-efficiency buck conversion in LED applications. The family offers various packaging options to suit different thermal and spatial constraints in modern lighting designs.

Replacement Considerations

Direct substitutes include LM3402HVMR/NOPB and LM3402HVMM/NOPB. Verify that the replacement maintains the same SOIC-8 PowerPAD footprint and electrical characteristics to ensure seamless integration.
