The NB671LAGQ-Z is a high efficiency DC/DC switching regulator with a maximum output current of 2A. It is designed using a totem pole topology, with two power output stages, a dedicated control and compensation stage, and a high accuracy voltage feedback control loop. It is capable of providing an output voltage range of 0.8V to 5.0V with up to 95% efficiency and very low quiescent current. The NB671LAGQ-Z is an ideal solution for applications that require a low noise, low power, and efficient power supply.

The NB671LAGQ-Z is a non-synchronous buck switching regulator with an operating frequency of up to 1MHz. It employs a pulse width modulation (PWM) control loop to regulate and control the output voltage. In this configuration, the peak current mode control loop uses the on-time control with ripple cancellation, fully protecting the NB671LAGQ-Z from current overshoot and other current-related risks. This makes it an ideal choice for powering low-noise and low-power systems, such as FPGAs, microcontrollers, and other battery-powered devices.

The NB671LAGQ-Z features an undervoltage lockout (UVLO) and an adjustable soft-start function. The UVLO prevents the device from operating when the input voltage is below the programmed voltage. The adjustable soft-start function slowly brings the output voltage to its programmed specified value to prevent it from in-rush current or overloading. The NB671LAGQ-Z also features an EN control pin to enable or disable the output voltage.

The NB671LAGQ-Z has many potential applications, such as in smartphones and tablets, wearable devices, battery chargers, and game consoles. It can be used to provide power to displays, processors, memory, sensors, and ASICs. It is also widely used in industrial automated equipment and embedded systems. In general, the NB671LAGQ-Z is an ideal choice when low output voltage, low noise, low power, and high efficiency are desired.

In summary, the NB671LAGQ-Z is a high-efficiency, non-synchronous DC/DC switching regulator with two power stages, a dedicated control and compensation stage, and a high accuracy voltage feedback control loop. It features an adjustable soft-start function, an undervoltage lockout, and an EN control pin. It has a wide range of applications encompassing smartphones and tablets, wearable devices, battery chargers, game consoles, and other low-noise and low-power systems.
