NCV8851-1DBR2G Description
The NCV8851-1DBR2G 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 fast transient response and tight regulation over wide input voltage and output load ranges. The IC NCV8851-1DBR2G 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 the 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.
