Overview of Texas Instruments UCC27200AD

The UCC27200AD from Texas Instruments is a high-frequency, high-side and low-side driver designed for efficient power management and conversion. This driver IC is capable of driving N-Channel MOSFETs and IGBTs in a half-bridge configuration, making it a versatile choice for a wide range of applications including switch mode power supplies, motor controllers, and class-D audio amplifiers.

Key Features

• High Voltage Capability: The UCC27200AD is designed to handle high voltages, with a bootstrap supply voltage up to 120V, providing reliable operation in high-voltage applications.
• Advanced Gate Drive: With a peak output drive strength of 4A for both the high-side and low-side drivers, it ensures fast switching of power devices, reducing losses and improving efficiency.
• Integrated Bootstrap Diode: The inclusion of an internal bootstrap diode simplifies the circuit design and reduces external component count, which can save space and cost on the PCB.
• Independent Inputs: Separate high-side and low-side inputs provide design flexibility, allowing for non-synchronous gate drive schemes or the use of advanced control techniques.
• Under-Voltage Lockout (UVLO): The UCC27200AD features a UVLO protection that ensures the driver operates only when the supply voltage is sufficient, thus protecting the power devices from potentially damaging undervoltage conditions.
• Cross-Conduction Prevention: A built-in dead-time prevents cross-conduction and shoot-through in the power stage, enhancing system reliability and efficiency.

Applications

The robustness and flexibility of the UCC27200AD make it an excellent choice for a variety of high-performance applications. It is particularly suited for power supplies in servers, telecom, and datacom equipment, as well as for driving motors in industrial and automotive settings. Additionally, its high efficiency and fast switching capabilities are ideal for modern audio amplifiers where fidelity and power control are critical.
