NCP6334BMT26TBG is a family of synchronous step-down switching regulators featuring high power density and high integration levels. Its integrated features and 80% high efficiency reduces output voltage ripple and makes it more cost-effective than stand-alone solutions. It can be designed with a variety of external components to meet various performance requirements, making it an ideal solution for a wide range of applications.

This family of regulators is designed for applications such as notebooks and netbooks, smart TVs and set-top boxes, automotive and industrial computing, server power systems and automated test equipment. Besides its high performance, it also offers power tracking, enable/disable, soft-start and auto-restart capabilities to enable system designers to optimize their power systems for exceptional performance and reliability.

The NCP6334BMT26TBG synchronous buck converter operates in a fixed frequency and works on a boot strap design, in order to achieve multiple output voltage and current levels. The input voltage range is from 8V to 18V, the maximum output current is 2A, and the output voltage is adjustable from 0.8V to the input voltage.

The NCP6334BMT26TBG utilizes an advanced control loop with a bottom-resistant current-mode control topology. This makes the regulator highly efficient and reliable, providing excellent power performance and very low output noise levels. The internal oscillator is stable over a wide temperature range and has an adjustable frequency range of 1Mhz to 2.6Mhz.

External MOSFETs are used to control the output voltage, depending on the required output current. For dynamic load applications, the device employs phase compensation to ensure stability. It also features cycle-by-cycle current limit protection and an internal foldback current limit, both to protect the device from overloads.

In order to ensure high efficiency, the device implements a single-phase PWM mode to keep the current in the output capacitor below 50% of the switching frequency. This ensures that the converter maintains its high efficiency during start-up and at heavy load conditions. The device also includes an internal soft start function, which ensures that the converter does not suffer from overload at start up.

The NCP6334BMT26TBG is highly integrated and includes many advanced features and protection functions such as over-current protection (OCP), Under-Voltage Lock-Out (UVLO) and Thermal Shutdown (TSD). The device also integrates high-precision trimming circuitry, allowing high accuracy and fast transient response in voltage regulation.

In conclusion, the NCP6334BMT26TBG is an ideal choice for applications requiring high power density and high integration levels, such as notebooks and netbooks, smart TVs and set-top boxes, automotive and industrial computing and server power systems. Its multiple protection functions and advanced control loop ensure high reliability, efficiency and performance.
