The UCC25600DR is a high-performance resonant mode controller designed by Texas Instruments for use in switch mode power supplies. This advanced IC is specifically engineered to facilitate the creation of highly efficient power solutions, making it an ideal choice for a wide range of applications, including telecommunication, server power supplies, and industrial systems.

Key Features

• Resonant Mode Switching: The UCC25600DR operates on a resonant mode switching principle, which reduces switching losses and improves overall efficiency. This mode of operation allows for zero-voltage switching (ZVS) or zero-current switching (ZCS), thereby reducing the stress on the power components and enhancing system reliability.
• Wide Frequency Range: It supports a broad switching frequency range, which is adjustable through an external resistor. This flexibility enables designers to optimize their power supply for specific applications and requirements.
• Internal Fault Protection: The device includes an array of protection features such as over-current protection, over-voltage protection, and thermal shutdown. These built-in mechanisms ensure the longevity and stable operation of the power supply under various conditions.
• High Drive Capability: The UCC25600DR can drive high-side and low-side MOSFETs with a robust gate drive strength, making it suitable for high-power applications.
• Versatile Supply Voltage: It is designed to operate over a wide supply voltage range, accommodating various input power sources and system requirements.
