NCL30002DR2G

Overview

The NCL30002DR2G is an AC-DC offline switcher IC designed for LED lighting applications. It utilizes a buck topology with no internal switch, operating within a supply voltage range of 10.2 V to 20 V. The device supports a single output channel and functions across a temperature range of -40°C to +125°C TJ. It is housed in an 8-SOIC surface-mount package.

Feature Summary

• Integrated AC-DC offline switching controller optimized for LED driver circuits
• Buck converter topology architecture without integrated power switch
• Single-channel output configuration for direct LED string driving

Applications

• General LED lighting systems
• Offline AC-DC conversion stages
• LED driver power supplies

Procurement Notes

Verify the specific suffix DR2G against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the design accommodates the absence of an internal switch by selecting appropriate external components. Confirm that the 10.2 V to 20 V supply range aligns with the target application's operational requirements.

Selection Notes

Select this component for designs requiring a buck-based AC-DC solution without internal switching losses. The 8-SOIC package suits space-constrained PCB layouts. Verify thermal management capabilities given the -40°C to +125°C junction temperature rating. Ensure the external circuitry supports the single-channel output requirement for the intended LED load.

Part Context

This part belongs to onsemi's family of AC-DC LED drivers. It complements other models like the NCL30000 series by offering a buck topology variant. The device targets cost-sensitive lighting applications where external switching elements are preferred or required for specific voltage regulation needs.

Replacement Considerations

Check for NCL30000 series variants if flyback topology is acceptable. Verify pin-to-pin compatibility with other 8-SOIC LED driver ICs from onsemi before substitution.
