Product Overview: UCC28085D - Texas Instruments

The UCC28085D by Texas Instruments is a versatile bi-directional peak-current-mode pulse-width modulator (PWM) controller designed for power supply applications. This high-performance IC is optimized for off-line and DC-to-DC converter applications that require efficient power management and a small form factor.

The UCC28085D operates with a supply voltage ranging from 8.5V to 14.5V, making it suitable for a wide array of power systems. It features a fixed-frequency operation that can be programmed via an external resistor, giving designers the flexibility to tailor the device to their specific needs. With a frequency range of 10kHz to 500kHz, the UCC28085D can be used in applications requiring either low-noise operation or compact size due to high-frequency operation.

One of the key features of the UCC28085D is its dual alternating outputs that allow for the implementation of either a push-pull, half-bridge, or full-bridge power converter configurations without the need for an external driver. This integrated functionality reduces external component count, saving space and cost on the PCB.

Additionally, the UCC28085D incorporates a number of protective features to ensure reliable operation under adverse conditions. These include under-voltage lockout (UVLO), over-current protection (OCP), and a programmable soft-start function that prevents inrush current during startup, enhancing system reliability.

The UCC28085D is available in an 8-pin SOIC package, providing a compact solution for space-constrained applications. Its operating temperature range of -40°C to +85°C allows it to perform reliably in a broad range of environments and applications.

Overall, the UCC28085D by Texas Instruments stands out as a robust and flexible solution for designers looking to optimize their power supply designs with a high-performance, feature-rich PWM controller.
