NCV891930MW01AR2G Description

Short technical summary and product information.

The NCV891930MW01AR2G from ON Semiconductor is a 2 MHz fixed-frequency, low quiescent current synchronous buck controller. It is designed for automotive applications and operates over an input voltage range of 4.5 V to 37 V. This controller utilizes peak current mode control for fast transient response and tight regulation across wide input voltage and output load conditions.

 

Key features include integrated spread spectrum for reduced EMI, adaptive non-overlap circuitry, and several protection features such as UVLO, current limit, short circuit protection, and thermal shutdown. The device supports synchronization to an external clock and has an adjustable soft-start feature. It is available in a 24-QFNW package with wettable flanks, suitable for surface mount applications.

 

This controller is well-suited for applications like radio and infotainment systems, instrument clusters, and ADAS. Its high switching frequency allows for small inductor values and ceramic output capacitors, contributing to a space-efficient design.
