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. Feedback compensation is internal to the device, permitting design simplification. The NCV891930 is capable of converting from an automotive input voltage range of 3.5 V (4.5 V during startup) to 18 V at a constant base switching frequency above the sensitive AM band, eliminating the need for costly filters and EMI countermeasures.
