LM3501TLX-16/NOPB

Overview

The LM3501TLX-16/NOPB is a synchronous step-up DC/DC converter designed for white LED applications. It operates with an input voltage range of 2.7V to 7V and provides a fixed output voltage of 16V. The device supports a switch current of 400mA and functions at a switching frequency of 1MHz. It is housed in an 8-DSBGA package, suitable for surface mount installation, and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Synchronous boost topology for efficient power conversion
• Fixed 16V output configuration for white LED driving
• Integrated high-side switch supporting 400mA current

Applications

• White LED lighting systems
• Portable electronic device backlighting
• Battery-powered LED modules

Procurement Notes

Verify the specific suffix '16' indicates the fixed 16V output variant. Confirm the DSBGA-8 package type matches the PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the target environment specifications before finalizing the component selection.

Selection Notes

Select this component when a fixed 16V output is required from a single-cell lithium battery or similar low-voltage source. The 1MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 400mA switch current limit when designing for higher brightness LED strings.

Part Context

This part belongs to the LM3501 family of synchronous step-up converters from Texas Instruments. These devices are optimized for driving white LEDs in portable applications, offering a compact solution with integrated power switches and control logic in a small footprint.

Replacement Considerations

LM3501TL-16/NOPB is a confirmed substitute part number with identical electrical characteristics and pinout compatibility.
