The UCC28085PWRG4 is a Micro-Power synchronous rectifying Buck controller suitable for various application fields. It combines linear, high-frequency and low-noise operating characteristics to make it versatile for many medium and high voltage applications. This controller was designed for use in AC/DC converters, offline switchers and other high power applications.

The UCC28085PWRG4 is a high current, high voltage synchronous rectifying Constant On-Time (COT) Buck controller. It features a very low power consumption, and is suited for powering multiple loads at once. The device uses a current mode control scheme and operates in a synchronous rectifying mode to improve efficiency. The maximum on-time of the COT control scheme can be adjusted externally by changing an external resistor, allowing the user to optimize their application.

The UCC28085PWRG4 includes many advanced features such as an adjustable external soft-start, and a low value (<1ms) fixed open-loop oscillator in combination with the COT control scheme, to maintain an optimal operating temperature and reduce electrical noise. Its Synchronization Pin (SYNC) supports synchronization of multiple UCC28085PWRG4 devices to reduce electrical noise, while an Internal Discharge (IDIS) pin ensures low quiescent current (Iq) and improves light load efficiency.

The UCC28085PWRG4 has overtemperature protection, integrated bias voltage regulation, output voltage supervision and adjustable current limit. It also features integrated soft start, a live-less power down mode and a low duty cycle operation mode for further flexibility.
