Product Overview: UCC27712D from Texas Instruments

The UCC27712D is a high-performance, high-speed MOSFET driver from Texas Instruments, designed to efficiently drive both the high-side and low-side N-Channel power MOSFETs in a synchronous buck or bridge power stage. This driver is particularly well-suited for applications requiring high power density and efficiency, such as in servers, telecom, and industrial power supplies, as well as automotive systems.

Key Features

• High-Current Driving Capability: The UCC27712D can deliver peak source and sink currents of up to 4 A and 4 A respectively, ensuring robust drive capability for a wide range of MOSFETs.
• Wide Supply Voltage Range: It operates over a supply voltage range of 10 V to 20 V, accommodating various power stages and ensuring flexible design options for different applications.
• High-Side and Low-Side Driver: With integrated high-side and low-side driver channels, the UCC27712D simplifies the design and reduces the component count in power conversion topologies.
• Fast Propagation Delays: The device boasts fast and matched propagation delays for both high-side and low-side channels, which helps in maintaining signal fidelity and improving overall system efficiency.
• Independent Inputs: Separate inputs for high-side and low-side gates provide design flexibility and support for various PWM control schemes.
• Cross-Conduction Prevention: The UCC27712D incorporates measures to prevent cross-conduction and shoot-through in the power stage, enhancing system reliability and performance.
• Robust Design: It features under-voltage lockout (UVLO) for both channels, ensuring that the MOSFETs are only driven when the supply voltage is sufficient.
