NCV887740D1R2G

Overview

The NCV887740D1R2G is an automotive-grade boost DC-DC switching controller IC manufactured by onsemi. It operates within a supply voltage range of 2V to 40V and features a fixed switching frequency of 170kHz. The device utilizes an 8-SOIC package with a width of 3.90mm. It supports a maximum duty cycle of 83% and includes control features such as current limiting and enable functionality. The component is qualified under AEC-Q100 standards and functions as a non-synchronous regulator with positive output configuration, suitable for surface mount installation.

Feature Summary

Automotive-grade design compliant with AEC-Q100 qualification standards
Integrated current limiting and enable control mechanisms
Fixed 170kHz switching frequency operation
Wide input voltage capability from 2V to 40V

Applications

Automotive start-stop systems
Step-up DC-DC conversion in vehicle electronics
Boost regulation for automotive power management

Procurement Notes

Verify the specific suffix D1R2G against official datasheets to confirm packaging and tape specifications. Ensure the procurement channel provides valid AEC-Q100 certification documentation for automotive compliance. Cross-reference the manufacturer part number with original equipment manufacturer requirements to prevent counterfeit components. Confirm lead times directly with authorized distributors as automotive grades may have extended availability windows.

Selection Notes

Select this component when a non-synchronous boost topology is required for automotive applications. The fixed 170kHz frequency simplifies external component selection compared to adjustable variants. Verify that the load current requirements do not exceed the internal switch capabilities implied by the non-synchronous design. Ensure the operating temperature range of -40°C to 150°C aligns with the specific environmental conditions of the target application.

Part Context

This part belongs to the NCV8877 series of automotive boost controllers. It shares functional similarities with other members like the NCV887711 and NCV887720 but differs in specific electrical characteristics and pinout configurations. The series is designed for robust performance in harsh automotive environments, offering reliable step-up voltage regulation for various onboard electronic loads.
