NCV3030BDR2G

Overview

The NCV3030BDR2G is an automotive-grade switching controller from onsemi, designed for high-frequency DC-DC conversion. It supports both Buck and Boost topologies within a single SOIC-8 package. The device operates with a fixed switching frequency of 2.4 MHz and accepts input voltages ranging from -300 mV to 40 V. It delivers a maximum duty cycle of 80% and includes internal compensation for stable regulation. Qualified under AEC-Q100 standards, it functions reliably across an extended temperature range from -40°C to +140°C, making it suitable for demanding automotive power management applications.

Feature Summary

• Supports versatile Buck and Boost converter topologies in a compact surface-mount package
• Automotive qualification ensures reliability in harsh environmental conditions
• High switching frequency enables the use of small external passive components

Applications

• Automotive infotainment system power distribution
• Vehicle lighting control circuits
• General automotive DC-DC step-down or step-up conversion

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and AEC-Q100 certification requirements match specific design needs. Check for moisture sensitivity handling instructions prior to assembly. Ensure supply chain stability as availability may be restricted.

Selection Notes

Select this controller when designing automotive power stages requiring combined buck-boost flexibility. The 2.4 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 80% maximum duty cycle meets the required voltage conversion ratio for the target application.
