The UCC25600D is a high performance DC-DC switching controller intended for use in a wide range of power supply applications. With its built-in adaptive loop compensation, it can reliably provide high power efficiency and dynamic response. The device is able to deliver up to 26V output voltage and 3A output current.

The UCC25600D is classified under the PMIC - Voltage Regulators - DC-DC Switching Controllers category as it primarily functions as a switching regulator for DC-DC conversion. This type of power management integrated circuit (PMIC) is designed for complex regulated power-supply systems that require accurate voltage regulation and noise reduction.

The UCC25600D includes a variety of features that are intended to reduce power consumption, increase system efficiency, and control the noise generated by high-frequency power supply applications. These features include an ultra-low quiescent current, adjustable switching frequency up to 1 MHz, low jitter current-mode control, and an integrated over-temperature protection.

The UCC25600D employs a current-mode control scheme that is well-suited to high power density requirements. Current-mode control (CMC) is a regulation method used in switched-mode power supplies, in which the voltage regulation function is performed by signalling current information instead of voltage information. This type of control is often used in high-power, high frequency applications because it provides faster transient response than voltage-mode control and has better immunity to line voltage variations.

The UCC25600D’s advanced control loop architecture ensures a high level of precision over all operating conditions. The adaptive loop compensation provides fast transient response and brings the output quickly back to regulation point after a load transients. Other features like cycle-by-cycle current limiting, adjustable soft-start, and programmable under-voltage, over-voltage, and over-temperature protections ensure the safe operation of the device and allow the system designer to optimize the performance of their power supply design.

To control the UCC25600D, the system designer can use the available programmable frequency, dead time, and power device switching duty cycle. The device includes an integrated low-side MOSFET driver to provide a low-cost, low-noise and low-ripple power supply design. The device’s high-performance current sensing eliminates external components, further reducing the total cost of the design.

The UCC25600D is a versatile and highly integrated DC-DC switching controller designed for a wide range of power supply applications. It can provide up to 26V output voltage and 3A output current and its current-mode control provides fast transient response and a better immunity to line voltage variations. The integrated features, such as the programmable frequency, dead time, and power device switching duty cycle, allow for greater design flexibility and system optimization. Furthermore, the integrated low-side MOSFET driver reduces system noise and cost. All these features make the UCC25600D an ideal choice for high power density power supply systems.
