NCV881930MW00AR2G Description

Short technical summary and product information.

The NCV881930MW00AR2G is a 410 kHz fixed-frequency, low quiescent current synchronous buck controller designed for automotive applications. It operates with an input voltage range of 4.5V to 37V, with a startup requirement of 3.5V and capability to withstand load dump conditions up to 45V.

 

This controller employs peak current mode control for fast transient response and tight regulation. It features integrated feedback compensation for design simplification and a high switching frequency that allows for small inductor values and ceramic output capacitors, enabling a space-efficient solution. Protection features include UVLO, current limit, short circuit protection, and thermal shutdown.

 

The device is housed in a 24-QFNW (4x4) package with wettable flanks, suitable for surface mounting. Its automotive qualification (AEC-Q100) makes it suitable for applications such as radio and infotainment, instrument clusters, and ADAS.

 

Key control features include current limit, enable, frequency control, and soft-start. The controller also supports clock synchronization.
