Here's a concise introduction to the UCC28C44DR: The Texas Instruments UCC28C44DR is a current-mode PWM controller designed for low-power offline flyback converters, LED lighting, and power supply applications that require precise current or voltage regulation. It features enhanced pin-to-pin compatibility with the UCx84x and UCx84xA family, operating at 1 MHz maximum frequency. This device offers fast overcurrent limiting, rail-to-rail output, and high accuracy. With a low startup current of 50 µA and an operating current as low as 2.3 mA, it's ideal for applications that prioritize power efficiency. The UCC28C44DR is particularly suited for telecom, server, and industrial markets due to its high reliability and performance.
Based on the product description provided, the features of the UCC28C44DR are:
These features make the UCC28C44DR suitable for applications that require precise current or voltage regulation, such as low-power offline flyback converters, LED lighting, and power supply applications. The device is also designed for high-efficiency and reliable performance in telecom, server, and industrial markets.
The UCC28C44DR has a SOIC-8 package, which stands for Small Outline Integrated Circuit - 8 pins. It's a surface-mount device with an 8-pin ceramic or plastic package.
According to the product information, the UCC28C44DR has an 8-pin SOIC package.
In terms of pin functions:
The device is a Current Mode PWM Controller with an SOIC package, specifically designed for low-power offline flyback converters and other power supply applications.
The manufacturer of the UCC28C44DR is Texas Instruments (TI). Texas Instruments is a leading semiconductor company that designs, manufactures, tests, and sells analog and embedded processing chips. The company was founded in 1930 and is headquartered in Dallas, Texas. TI is a global leader in the development and manufacturing of semiconductors, with a wide range of products used in various industries such as automotive, industrial, medical, and consumer electronics.
According to the product information, the application areas of UCC28C44DR are:
According to the product description, the UCC28C44DR is an enhanced replacement for the UCx84x and UCx84xA family with pin-to-pin compatibility. Therefore, the equivalent products of UCC28C44DR are likely to be the UC2844A, UC2844, or other similar devices from Texas Instruments' UCx84x/UCx84xA family.
