PMIC (power management integrated circuit) technology is a type of integrated circuit used to control and manage the operation of power handling equipment. AC DC converters, offline switchers, and the NCP1050ST136T3 are just a few of the components used to achieve power management and operational efficiency. This article will focus on the NCP1050ST136T3, its application fields and working principle.

NCP1050ST136T3 Overview

The NCP1050ST136T3 is an energy-efficient, compact power switching regulator that is suitable for many power management applications. It is designed to maintain an output voltage of a fixed, regulated level, regardless of the supply voltage and load conditions. The device is capable of handling input voltages between 4.5V and 12V and can provide a regulated output voltage of up to 5V. It also features adjustable over-temperature, under-voltage, over-voltage and over-current protections and a current fold-back feature which makes it suitable for applications that need reliable protection against excessive load and temperature variations. The NCP1050ST136T3 is available in a thermally-enhanced and industry-standard 5 mm × 7 mm package.

Application Fields

The robust and versatile design of the NCP1050ST136T3 makes it suitable for a variety of applications requiring an adjustable or fixed voltage source. These applications include voltage regulation for circuits that require use of a USB power source, such as smartphone or laptop charging circuits or battery charging solutions. In addition, the device is suitable for a range of applications where space is limited, such as consumer electronics (TV, monitor, etc.), industrial and automotive electronics, as well as consumer and industrial power converters. The NCP1050ST136T3 is also suitable for other applications such as battery operated systems, high-efficiency DC/DC power conversion, and power management solutions.

Working Principle and Features

The device works by regulating the input voltage of DC, thereby providing a constant, regulated voltage output. The NCP1050ST136T3 uses a unique “third-order” loop compensation technique to provide accurate and fast load/line/temperature transient responses. The device also has an integrated error amplifier module, pass transistor and multiple-output analog and digital control blocks. This allows for high-precision, programmable output regulation.

Thanks to its integrated protection features and fixed or adjustable voltage options, the NCP1050ST136T3 provides users with an energy-efficient and reliable power management solution. With its multiple built-in protection features, the device is also suitable for a variety of applications where over-temperature, under-voltage, over-voltage and over-current conditions are a concern.

In addition, the NCP1050ST136T3 also features a low dropout (LDO) mode which enables operation at very low input voltages. This mode allows the device to maintain a regulated output voltage when the input voltage drops over time. This makes it an ideal solution for applications such as battery-powered devices that require a regulated voltage even as the battery voltage drops.

The NCP1050ST136T3 also includes an adjustable current fold-back feature that helps to protect the device in the event of a current overload. This feature activates when the peak output current exceeds a certain limit and helps to reduce current consumption and improve the overall efficiency of the device.

Conclusion

The NCP1050ST136T3 is a robust and reliable AC to DC power switch regulator that can be used in a variety of applications that require regulated output voltages. It features adjustable output voltage, over-temperature, under-voltage, over-voltage and over-current protections and a current fold-back feature which make it suitable for a wide range of applications. It is also suitable for applications that require a low dropout mode, such as battery-powered devices, and its integrated protection features make it an excellent choice for high-efficiency DC/DC power conversion and power management solutions.
