UCC28C40DGKR is a controller IC specifically designed to regulate voltages in a range of portable devices and automotive electronics applications. It is part of a family of integrated circuit products produced by Texas Instruments and is classified as a PMIC (Power Management Integrated Circuit) with special focus being given to Voltage Regulators, DC DC Switching Controllers.

The UCC28C40DGKR is primarily used as an adjustable voltage regulator for portable product applications. It has been designed for applications requiring a low number of external components and is noted for its ability to switch and regulate low voltages. It can be used to provide an adjustable supply voltage from 0.8V to 3.5V and is suitable for load dumping applications. The UCC28C40DGKR has a large number of functional features, such as current limit detection and thermal shutdown protection, making it suitable for a variety of highly challenging and demanding applications.

The device has two pins to enable the system to operate in a synchronous or asynchronous mode. The device can be programmed for power up, power down, and for operation in either Burst Mode or Power Save Mode. It also features an enable pin with a logic low enable level which triggers an output voltage dropped to 0.8V. This makes the device suitable for a large number of portable applications.

A basic working principle of the UCC28C40DGKR is that it converts a DC input voltage to one or more outputs. The inputs to the device can be a battery, a regulated DC power supply, or a wall adapter. When these are connected to the input terminals of the device, the output voltage is regulated. The output voltage can be adjusted by settings on the two pins to enable the device to operate in synchronous or asynchronous mode.

The output voltage is regulated through the use of a Pulse Width Modulation (PWM) technique, also known as pulse-frequency modulation. This is performed by the internal control circuit which monitors the inputs and outputs, and regulates the output voltage accordingly. The UCC28C40DGKR also has an external current limit switch, enabling the user to define their own operating parameters.

The UCC28C40DGKR is capable of regulating a wide range of current levels, from only 100 mA to more than 5 A at a typical output load of 5 ohms. It has a high power efficiency rating, and is capable of exceeding 90% with a regulated output voltage up to 3.5V. It also features adjustable switching frequency, enabling the user to tune the performance of the device for specific applications.

The UCC28C40DGKR features a number of protective features, such as thermal shutdown, current limit detection, over voltage protection and open loop protection. These features make it ideal for applications where reliability and protection of components is critical, such as automotive electronics and portable products. It also has a built in auto reset function, as well as several modes of operation.

The UCC28C40DGKR is an integrated circuit specifically designed to regulate voltages in demanding and challenging applications. It is part of a family of products produced by Texas Instruments and is classified as a PMIC (Power Management Integrated Circuit) with special focus being given to Voltage Regulators, DC DC Switching Controllers. Its adjustable, low voltage, adjustable current limits capabilities and protective features make it ideal for use in a wide range of portable product and automotive electronics applications.
