Application Field

NCP6133MNTWG is an ideal choice for applications requiring efficient and reliable power conversion. It is an ideal choice for demanding telecom, networking, and datacenter applications operating with a wide range of supply voltages. Typical applications include telecom power supplies, power over Ethernet (PoE) systems, FET motors, tachometers, LED lighting, and automotive systems.

Working Principle

The NCP6133MNTWG is a non-synchronous buck converter that operates by drawing current from the input source, storing this energy in an inductor, and then discharging it to the output to create a regulated voltage. The buck converter features a high frequency oscillator, a PWM comparator, and an integrated power switch with gate driver. The integrated power switch controls current flow from the input to the output to provide the required output voltage. Since the power switch is part of the converter, the efficiency is greatly improved and allows for higher output currents than traditional linear regulators.

The NCP6133MNTWG incorporates a dynamic voltage positioning loop designed to maintain the output voltage at its desired level within a ±3% accuracy, even at light loads. This feature allows it to maintain a constant output voltage over a wide range of input and output voltages. The switching frequency of the NCP6133MNTWG can be adjusted between 250 kHz and 2 MHz using an external resistor, enabling the design of power-efficient systems.

The NCP6133MNTWG also features a comprehensive range of protection features to safeguard the device and the system. These include over temperature protection, under voltage lockout, thermal shutdown, and over current protection. These protection features make the NCP6133MNTWG an ideal choice for high reliability applications in harsh environments.

Conclusion

In conclusion, the NCP6133MNTWG is a high-performance, low quiescent current, and feature-rich switch-mode power converter. It is suitable for a wide range of applications, such as telecom power supplies, PoE systems, LED lighting, FET motors, and automotive systems. Its integrated power switch and gate driver provide excellent efficiency while its comprehensive range of protections ensure high reliability and safety. With its wide input/output voltage range and adjustable switching frequency, the NCP6133MNTWG is an ideal choice for demanding power converters.
