Product Overview: Texas Instruments UCC27210DR
The UCC27210DR by Texas Instruments is a high-frequency, high-side and low-side driver designed for use in a variety of power conversion applications. This advanced MOSFET driver is capable of driving a wide range of power MOSFETs and IGBTs and is particularly suited for applications that require efficient and reliable switching performance, such as synchronous buck converters, active clamp forward converters, and full-bridge power topologies.
Key Features
- High-Voltage Capability: The UCC27210DR is designed to handle up to 120V, making it suitable for high-voltage applications.
- Robust Output Drive: With a peak output current of 4A for both the high-side and low-side drivers, this device can effectively switch power transistors with speed and efficiency.
- Independent Inputs: Separate inputs for high-side and low-side gates provide design flexibility and allow for precise control over switching actions.
- Bootstrap Operation: The integrated high-voltage bootstrap diode enables high-side gate drive with a single power supply, simplifying the circuit design.
- Under-Voltage Lockout (UVLO): Both high-side and low-side drivers have UVLO features to ensure the device operates only when the supply voltage is sufficient.
- Cross-Conduction Prevention: Built-in dead-time control helps prevent shoot-through by ensuring that both high-side and low-side FETs are not on simultaneously.
