The UCC2585D integrated circuit is a DC-DC switching controller from the PMIC (Power Management Integrated Circuit) family of voltage regulators. Specifically, the chip is part of the DC-DC switching controllers product line. It has been designed primarily to enhance the range of available DC-DC controller configurations.

It is primarily designed to provide integrated, high-efficiency control of synchronous DC to DC buck converters. It can also be configured as a synchronous buck boost, high side buck, low side buck, and dual phase synchronous buck converter. It features low output voltage ripple even at high current levels, and is capable of achieving a range of output voltages ranging from 0.8V to 16V. It also supports a wide range of input voltages, allowing the user to configure it for a single voltage source or for a split-path dual source.

The UCC2585D makes use of various proprietary technologies including Automotive Pulse Position Modulation (APiM) and Powerover Simultaneous BuckBoost (PPSB). APiM allows for dynamic control of the peak current capability of the converter by monitoring the current system demand, while PPSB provides a low quiescent current design over a wide voltage range. This allows for highly efficient operation.

The main application of the UCC2585D is in various power supply designs, including computers, mobile devices, and automobiles. Its wide range of input voltage options allows it to be used in almost any kind of power supply system. Its versatile configuration makes it ideal for advanced power supply designs, as it can be easily adapted to accommodate specific designs. Its low output ripple and power efficiency also make it an ideal choice for energy efficient systems.

The working principle of the UCC2585D is based on the use of pulse-width modulation (PWM) for the control of switching elements. By using this technique, the chip is able to control the output voltage with a high degree of accuracy. The PWM is generated internally by a proprietary, programmable digital core. This core can be configured to modulate the output voltage according to user-defined settings. Additionally, the core features numerous protection features such as over-temperature, current regulation and short-circuit protection.

Other features of the UCC2585D include a range of alarm and warning signals and a low logic power consumption. The digital core can also be configured to operate with either a single rail and dual rail power supply, allowing for improved flexibility. Additionally, the chip integrates a software-configurable digital filter that allows for fast transient response and high-resolution output voltage control.

In summary, the UCC2585D is a DC-DC switching controller from the PMIC (Power Management Integrated Circuit) family of voltage regulators. It has been designed primarily to enhance the range of available DC-DC controller configurations. It makes use of various proprietary technologies including Automotive Pulse Position Modulation (APiM) and Powerover Simultaneous BuckBoost (PPSB) for enhanced control and efficiency. The chip integrates a software-configurable digital filter that allows for fast transient response and high-resolution output voltage control. Its primary application is in various power supply designs, including computers, mobile devices, and automobiles.
