LM2753SDX/NOPB

Overview

The LM2753SDX/NOPB is a Texas Instruments LED driver IC utilizing a switched-capacitor charge pump topology. It provides a regulated output current of 400 mA with an input voltage range of 3 V to 5.5 V. The device operates at a switching frequency of 725 kHz and supports PWM dimming for brightness control. Designed for camera flash applications, it features an internal switch and delivers an output voltage between 4.75 V and 5.25 V. The component is housed in a 10-SON (3x3) package and functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrates a high-efficiency switched-capacitor charge pump for compact LED driving solutions
Supports precise PWM dimming control for adjustable flash intensity
Includes an internal power switch to minimize external component count

Applications

Camera flash lighting systems
Mobile device illumination circuits
Compact LED driver modules

Procurement Notes

Verify the specific suffix 'SDX' indicates tape-and-reel packaging when sourcing. Confirm the 'NOPB' designation ensures lead-free and RoHS compliance as per manufacturer standards. Cross-reference the exact part number against official Texas Instruments documentation to ensure compatibility with intended PCB footprint and thermal requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring a fixed 400 mA output current from a single-cell lithium-ion battery source. The 725 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the design accommodates the 10-SON package dimensions and thermal dissipation needs for continuous operation within the specified ambient temperature range.

Part Context

This device belongs to the LM2753 series of LED drivers from Texas Instruments. It is specifically engineered for portable electronics where space constraints are critical. The series utilizes charge pump technology to step up voltage efficiently while maintaining constant current regulation for consistent LED performance.
