Details
The NB671GQ-Z is an adjustable buck regulator integrated circuit (IC) capable of delivering up to 6A of output current. It is housed in a 16-lead QFN (quad-flat no-leads) package, making it suitable for applications where space is limited and thermal performance is critical. This IC operates by taking a higher input voltage and efficiently converting it to a lower, adjustable voltage output. The adjustable feature allows for flexibility in setting the output voltage to a desired level, making it versatile for various applications. The NB671GQ-Z incorporates advanced control features such as voltage mode control and pulse-width modulation (PWM) operation, ensuring stable and precise output regulation under different load conditions. It also includes built-in protection features such as overcurrent protection, thermal shutdown, and input undervoltage lockout to safeguard both the IC and the connected circuitry from damage in case of faults or abnormal operating conditions.
