NCV8851-1GEVB:  Adjustable Output Synchronous Buck Controller Evaluation Board

The NCV8851-1 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 a wide input voltage range (4.5 V to 40 V) and is capable of 10 to 1 voltage conversion at 500 kHz. Additional controller features include undervoltage lockout, internal soft start, low quiescent current sleep mode, programmable frequency, SYNC function, average current limiting, cycle-by-cycle overcurrent protection and thermal shutdown.
