The NB679GD-Z is a multi-functional Voltage Regulator module (VRM) that is part of a larger family of products developed by National Semiconductor. It is classified as a linear and switching regulator, as well as a Pulse Width Modulation (PWM) control, and is designed to regulate the voltage input to a system. It is used in a wide range of applications, such as power supplies, charge controllers, and battery management systems.

The NB679GD-Z is designed to provide four different voltage outputs. These range from 3.3V, 5V, 8V, and 9V. It is also capable of supplying a maximum output current of up to 10A. The number and range of voltages supplied by the unit, as well as the maximum output current, makes it suitable for a wide range of applications in various industries.

The NB679GD-Z is equipped with several features to ensure reliable operation. It has built-in overvoltage and current protection to prevent the module from malfunctioning and damaging any connected system. The unit also has power good and power bad signal alarms, to indicate when an overcurrent or overvoltage situation occurs. Additionally, the sequencer is integrated within the unit and can be set to control the output voltages in any order.

The NB679GD-Z is controlled by an internal operating system. This system uses a simple two-wire interface, which allows it to communicate with the host processor. The system constantly monitors the system conditions and regulates the output voltages using the commands sent by the host processor.

The NB679GD-Z works in two different modes. In the Linear Regulation mode, the system regulates the output voltages using an internal hysteresis loop. The system constantly monitors the output voltages, and if any exceed the preset limits, it will adjust them automatically. This mode is suitable for applications where the output voltage is critical.

The NB679GD-Z also works in the PWM Control mode. In this mode, the system uses voltage feedback and a Pulse-width Modulated (PWM) signal to regulate the output voltages. This mode allows the system to achieve a finer control over the output voltages. The PWM signals can be further adjusted by the host processor to further fine-tune the output voltages.

In summary, the NB679GD-Z is a multi-functional linear and PWM Voltage Regulator module capable of regulating up to four different voltages with a maximum output current of 10A. It is equipped with several features to ensure reliable operation and is easy to use, making it suitable for a wide range of applications.
