The UCC2813PW-3 is a type of PMIC (Power Management IC), widely used in voltage regulation and DC DC switching controller applications. It has a wide range of features, some of which are unique to its family of ICs.
This microcontroller is a mixed signal integrated circuit capable of providing extensive protection functions. The external resistor by setting it in the circuit can be connected to the external resistor and this would make the circuit highly reliable. The IC is designed with a built-in 500V transient voltage suppressor (TVS) protection. This gives the IC an ability to detect and respond to an external voltage surge. It can provide protection against overvoltage and undervoltage conditions. The IC also features a low-consumption standby mode, which reduces the current draw and increases its efficiency.
The UCC2813PW-3 operates by implementing a standard Boost and Inverting configuration for DC-DC converters. It works by supplying a fixed regulated output voltage from an input voltage ranging from 3V to 32V. The fixed output voltage can be adjustable from 3.3V to 28V, according to the input and the external resistor setting. The adjustable output voltage allows the use of the IC for various applications ranging from computer peripherals to medical sensing systems.
One of the attractive features of the UCC2813PW-3 is its wide operating temperature range. It can remain intact and stay functional at temperatures ranging from - 40°C to 125°C. This feature enables the use of the IC in the desired temperature sensitive applications. It is also designed to survive different fault conditions like overvoltage, over temperature, and over current, without causing any damage to the device.
The UCC2813PW-3 uses pulse width modulation (PWM) control as its primary method of operation. With PWM, the output voltage is regulated by adjusting the duty cycle of the switching signals through the control logic. This helps to maintain a constant output voltage, with a high efficiency rate. The IC also implements a high-frequency oscillator and a double switching power stage for the generation of required switching signals. These signals are then used to control the PWM demand.
This IC also offers an active current limit feature for increased safety. It optimizes the output voltage and enables the safe rejection of large current overloads, allowing for protection against faults such as short circuit and excessive current discharge. This feature is especially useful for applications requiring primary over current protections.
Overall, the UCC2813PW-3 is a powerful and reliable device for providing voltage regulation and DC DC control. It offers a wide range of features and possibilities with its advanced protection and PWM control capabilities. This makes it the ideal solution for powering different devices while providing optimal regulation and control security.
