AC/DC converters are a type of device, also referred to as an AC-DC converter, that converts alternating current (AC) to direct current (DC). Automotive converters, computer power supplies, and home appliances are just a few examples of products that commonly use AC-DC converters. The NMP1K2-C#CEEC-00 AC-DC converter is an efficient, reliable, and compact solution for a wide variety of applications.

General Description

The NMP1K2-C#CEEC-00 is a highly efficient AC-DC switch converter which is specifically designed for low-power (< 10 W), high-frequency applications. This device is based on a quasi-resonant flyback topology and features an operating frequency up to 150 KHz. It offers flexibility with regard to output voltage, providing adjustable output voltage up to 24V and power up to 10W. It integrates a wide range of protection and fault detection circuits, including short-circuit protection, overtemperature protection and input under-voltage lockout. The device is housed in an ultra-small TO-220-4L + DFN 2×2-8L package.

• Output voltage range: 0.6-24V
• Output power: up to 10 Watts
• Operating frequency: up to 150 KHz
• Integrated protection and fault detection circuits
• Small package size
• High efficiency up to 94%

Application Fields

The NMP1K2-C#CEEC-00 is suitable for applications that require high efficiency and a low profile, such as consumer electronics, set top boxes, and LCD TVs. The device has been developed to replace traditional linear power supplies, thanks to its high efficiency and wide range of protection features. Furthermore, the device’s small package size and high switching frequency make it an ideal choice for a wide range of application fields.

Working Principle

The NMP1K2-C#CEEC-00 AC-DC converter is based on a quasi-resonant, flyback topology. To achieve high efficiency at different load levels, the device operates in three different modes: burst mode, active mode, and stand-by mode. During burst mode, the device switches off the main power switch and only enables a low-power quiescent switch to provide output power. When the load increases, the device switches to active mode, where both the quiescent and main switches are enabled. Finally, when the load decreases, the device enters stand-by mode, where only the quiescent switch is enabled. This results in high efficiency at different power levels and low power consumption in stand-by mode.

Conclusion

The NMP1K2-C#CEEC-00 AC-DC converter is an efficient and reliable solution for low-power applications. It offers adjustable output voltage up to 24V, output power up to 10W, and a wide range of protection and fault detection circuits. Due to its high efficiency and small package size, the device is suitable for a wide range of applications, from consumer electronics to set top boxes and LCD TVs. Furthermore, its high switching frequency and quasi-resonant, flyback topology ensure high efficiency at different load levels.
