Synchronous Buck Controller, Automotive Grade NCV8856A The NCV8856A is an adjustable output, synchronous buck controller, which drives dual N channel MOSFETs, ideal for high power applications.

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

The IC incorporates an internal fixed 6.0 V low dropout linear regulator (LDO), which supplies charge to the switch mode power supply’s (SMPS) bott
