NB675GL-P is a DC-DC buck switching regulator designed to provide clean, adjustable and regulated power to many applications. It uses a PWM-type power control architecture to provide wide adjustable output voltages, with a wide range of current and voltage ratings which support a variety of applications. This buck-mode power regulator also offers a wide range of adjustable over-current, over-voltage and short-circuit protection.

This regulator is particularly suitable for many applications where very low EMI (electromagnetic interference) and extremely clean power source are important. These applications include laptop computers, high-end test equipment and other equipment requiring low noise and high efficiency. Additionally, the NB675GL-P is often used in medical devices, safety,military and industrial equipment, telecommunication systems and other mission-critical applications.

The NB675GL-P has two models available, one with a built-in forward converter, and the other with an external forward converter. The built-in forward converter allows higher output voltages and improved efficiency, whereas the external forward converter provides a greater degree of flexibility and adjustability. The NB675GL-P is capable of delivering regulated output voltages from an input voltage range of 4.75V to 16V and can accept input currents up to 15A and output currents up to 3A.

The NB675GL-P employs a pulse-width modulation (PWM) control architecture to provide low noise, smooth output voltage stability and excellent transient response. This control architecture enables the regulator to be programmed to provide a wide range of output voltage settings, including programmable over-current protection, adjustable over-voltage protection and adjustable short-circuit protection. Additionally, the NB675GL-P integrates other features such as under-voltage lockout, short-circuit mode protection and thermal energy management.

The NB675GL-P uses a switching element, typically a MOSFET, which secures the output voltage. When in normal operation, the voltage regulator switches at a high frequency of up to 1 MHz, enabling it to produce a very clean and efficient output signal. However, when the regulator senses an overload condition, it adjusts its duty cycle to reduce power output and shuts off if the overload is sustained for too long.

The NB675GL-P also provides additional features such as overtemperature, over-voltage, and under-voltage protection, and a current-limit circuit with independent current limit. This allows the NB675GL-P to monitor the current flow and prevent damage caused by an excessive current load. Additionally, the NB675GL-P supports its own self-protection feature which automatically shuts off the power if an over-temperature or over-voltage condition occurs.

Overall, the NB675GL-P is an ideal DC-DC buck switching regulator, offering the perfect combination of adjustable voltage, cleanness, and protection, making it an ideal choice for many applications requiring high performance and reliable power delivery.
