Low Quiescent Current 410 kHz Automotive Synchronous Buck Controller NCV881930 The NCV881930 is a 410 kHz fixed frequency low quiescent current buck controller with spread spectrum that operates up to 38 V (typical).

It may be synchronized to a clock or to separate NCV881930.

Peak current mode control is employed for fast transient response and tight regulation over wide input voltage and output load ranges.

Feedback compensation is internal to the device, permitting design simplificatio

NCV881930 Features

* such as UVLO, current limit, short circuit protection, and thermal shutdown are provided. High switching frequency produces low output voltage ripple even when using small inductor values and an all

* ceramic output filter capacitor, forming a space

* efficient switching solution. (2 MHz
