LM3502ITLX-35/NOPB

LED Driver IC Overview

The LM3502ITLX-35/NOPB is a step-up converter designed for white LED applications. It features a 1 MHz switching frequency and supports PWM dimming. The device provides a fixed output voltage of 35 V with a switch current rating of 750 mA. It operates within a temperature range of -40 °C to +85 °C and utilizes a uSMD package.

LED Driver IC Feature Summary

• Integrated step-up converter topology optimized for LED driving
• Supports pulse-width modulation (PWM) dimming control
• Fixed high-voltage output configuration

LED Driver IC Applications

• White LED backlighting systems
• Portable electronic display illumination
• LED driver circuits requiring fixed high voltage

LED Driver IC Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the operating temperature range and package type match the design requirements. Ensure the input voltage source supports the required headroom for the step-up operation at the specified load conditions.

LED Driver IC Selection Notes

Select this component when a fixed 35 V output is required for LED strings without external feedback adjustment. The integrated 1 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 750 mA switch current capability meets the peak inductor current demands of the target application.

LED Driver IC Part Context

This part belongs to the LM3502 family of LED drivers from Texas Instruments. These devices are specialized power management ICs intended to drive high-brightness LEDs efficiently. The ITLX-35 variant specifically denotes the fixed output voltage version in the series.

LED Driver IC Replacement Considerations

Check for LM3502 variants with different output voltages or packages if system constraints change. Verify pinout compatibility before substituting with other TI LED drivers.
