The NCV8851-1DBR2G from ON Semiconductor is an adjustable output, synchronous buck controller that drives dual N-channel MOSFETs, making it suitable for high power applications. It employs average current mode control for fast transient response and tight regulation across wide input voltage and output load ranges.
Key features include a wide input voltage range of 4.5 V to 40 V, an internal fixed 6.0 V low-dropout linear regulator (LDO), undervoltage lockout (UVLO), internal soft-start, and low quiescent current in sleep mode. The controller offers programmable fixed frequency operation from 170 kHz to 500 kHz, with external clock synchronization up to 600 kHz. It also incorporates average current limiting (ACL), cycle-by-cycle overcurrent protection (OCP), and thermal shutdown (TSD).
This device is housed in a 20-TSSOP package and is designed for surface mount. It is suitable for automotive systems requiring high current and pre-regulated supplies for low-voltage SMPSs and LDOs. The NCV8851-1DBR2G is a Pb-Free device.
Additional specifications include a 0.8 V ±2% reference voltage and a minimum high-side gate off-time of 180 ns. The operating temperature range is -40°C to 150°C.
