Overview

The NCL30160DR2G is a DC-DC LED driver IC from onsemi, featuring an integrated power MOSFET in an SOIC-8 package. It operates as a buck converter with a fixed switching frequency of 1.4 MHz and supports an input voltage range of 8 V to 40 V. The device delivers a regulated output current of 1 A, suitable for high-brightness LED applications. It functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Integrates a power MOSFET to minimize component count and board space
• Supports PWM or analog dimming for flexible light control
• Enables capacitor-less output design through average current control

Applications

• Automotive lighting systems
• Industrial illumination fixtures
• General purpose LED drivers

Procurement Notes

Verify the specific suffix DR2G against the official datasheet to confirm packaging details and compliance status. Ensure the application circuit matches the required input voltage range of 8 V to 40 V. Confirm that the thermal management strategy accommodates the specified operating temperature limits for the intended environment.

Selection Notes

Select this component when a compact solution with an internal switch is required for buck topology LED driving. The 1.4 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1 A output capability and the support for both PWM and analog dimming methods when designing the control interface.
