The UCC28086DG4 is an advanced power switch controller designed to provide voltage conversion and current limiting in multiple applications. It is generally classified as a PMIC (Power Management integrated circuit) and more specifically under Voltage Regulators, DC/DC Switching Controllers. The UCC28086DG4 is optimized for buck (step-down) and buck-boost (inverting) power conversion. It can also be used for boost voltage converters and as a high frequency DIP/SIP low dropout (LDO) regulator.

The UCC28086DG4 integrates a high and low-side power switch MOSFET drivers. The low-side driver features a synchronized pulse-width modulation (PWM) buck converter and an adaptive shoot-through preventer, while the high-side driver features a current mode control (CMC) regulation loop. Together, they provide converters with fast transient response and full protection features. Additionally, UCC28086DG4 integrates an integrated high-voltage start-up circuit, low-on resistance external MOSFET, fault protections and voltage sensing functions.

The UCC28086DG4 has comprehensive application field. It is widely used for powering and protecting multimedia notebooks, personal computers, servers, graphic processors, hard disc drives, dedicated graphics cards and various consumer electronics. It is also used for driving and controlling several types of backup and secure power systems, such as uninterruptible power supplies (UPS) and point-of-load (POL) regulators. It can also be used for motor control for power tools, handheld systems, toys, battery chargers and other dc applications.

The working principle of the UCC28086DG4 is to convert one form of energy into another. Using the low-side and high-side power switch MOSFET drivers, a buck-boost voltage converter is able to provide a wide range of output voltage, and the current mode control loop ensures fast transient response. The high-voltage start-up circuit eliminates the additional circuitry needed for low-voltage operations, and the low-on resistance external MOSFET allows low power consumption and reduces power loss. Additionally, the voltage sensing capability ensures that the output voltage is always kept within the specified limits and that the system is free from short circuit and over-voltage conditions.

On top of the fast transient response, excellent start-up current control and protection features, the UCC28086DG4 also offers extra features, such as a reverse current limit protection and a voltage limiting function. This can be used for applications that require extra protection against over-voltage and over-current. Finally, the UCC28086DG4 also integrates a dedicated end of life detection and alert, ensuring that the system is always running at optimal performance.

In conclusion, the UCC28086DG4 is a highly advanced power switch controller designed for multiple applications. It is generally classified as a PMIC and more specifically under Voltage Regulators, DC/DC Switching Controllers. The device provides fast transient response, excellent start-up current control and protection features, a wide range of output voltage and an integrated high-voltage start-up circuit. It is widely used for powering and protecting multimedia notebooks, personal computers, servers, graphic processors and other consumer electronics, and it is also used for driving and controlling backup and secure power systems. Additionally, the device offers features such as a reverse current limit protection and a voltage limiting function, as well as end of life detection and alert.
