NCS29001DR2G

Overview

The NCS29001DR2G is a step-up DC-DC controller designed for LED driving applications, manufactured by onsemi. It operates within an input voltage range of 8.5V to 18V and supports PWM dimming control. The device features a switching frequency between 100kHz and 500kHz and provides a single output channel capable of delivering up to 500mA. It is housed in a 14-pin SOIC package with a width of 3.90mm. The component is qualified for commercial temperature ranges from -40°C to +85°C and is scheduled for obsolescence.

Feature Summary

Integrated boost topology for efficient LED current regulation
Supports pulse-width modulation (PWM) dimming operations
Designed specifically for backlight and LED driver applications

Applications

LED backlight systems
General LED lighting drivers
Boost converter circuits for illumination

Procurement Notes

Verify end-of-life status before design finalization as the manufacturer has scheduled this part for discontinuation. Confirm that the 14-SOIC footprint matches existing PCB layouts. Ensure supply chain strategies account for potential availability constraints due to the obsolescence notice. Validate compatibility with system input voltage ranges of 8.5V to 18V.

Selection Notes

Select this component for applications requiring a compact boost solution for LED strings within the specified voltage window. Consider the 500mA output capability when sizing external inductors and diodes. Evaluate the thermal performance in the SOIC-14 package against expected power dissipation. Verify that the fixed frequency range aligns with electromagnetic interference requirements.

Part Context

This part belongs to onsemi's portfolio of power management integrated circuits focused on LED driving. It serves as a dedicated controller for step-up topologies, distinguishing itself from general-purpose regulators by optimizing for constant current LED loads. The series targets cost-sensitive consumer electronics and display backlighting markets.
