NCV891930 Description
Low Quiescent Current 2 MHz Automotive Synchronous Buck Controller NCV891930 The NCV891930 is a 2 MHz 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 NCV891930. Peak current mode control is employed for fast transient response and tight regulation over wide input voltage and output load ranges.
