Automotive Grade

Synchronous Buck

Controller

The NCV8856 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) bottom gate driver, limiting the

power lost to excess gate drive. The IC is designed for operation over

an input voltage range of 4.5 V to 38 V and is capable of 10 to 1

voltage conversion at 500 kHz.

Additional controller features include undervoltage lockout,

overvoltage shutdown, internal soft−start, low quiescent current sleep

mode, programmable frequency, SYNC function, average current

limiting, cycle−by−cycle overcurrent protection and thermal

shutdown.
