UCC27710DR Typical application Circuitry

UCC27710DR is a high-side and low-side gate driver IC, commonly used in power electronics applications for driving MOSFETs and IGBTs in synchronous buck or boost converters, half-bridge converters, and other power management circuits.

Application Scenario:

In a synchronous buck converter design, UCC27710DR can be utilized to drive the high-side and low-side MOSFETs for efficient power conversion in applications such as DC-DC voltage regulation.

Circuit Design:

To design a synchronous buck converter using UCC27710DR, follow these detailed steps:

1. High-Side Gate Driver Connection:

Connect the VDD pin of UCC27710DR (pin 4) to the supply voltage (typically 12V or 15V). Connect the Bootstrap capacitor (typically 0.1μF) between the VDD pin and the HO pin (pin 5). Connect the HO pin to the gate of the high-side MOSFET.

2. Low-Side Gate Driver Connection:

Connect the VSS pin of UCC27710DR (pin 6) to the ground. Connect the LO pin (pin 2) to the gate of the low-side MOSFET.

3. Bootstrap Diode Connection:

Connect a Schottky diode between the HO pin (pin 5) and the VS pin (pin 7) of UCC27710DR. Connect the VS pin to the source of the high-side MOSFET.

4. Feedback and Control:

Implement feedback and control circuitry to regulate the output voltage. Connect the FB pin (pin 1) of UCC27710DR to the feedback network.

5. Protection and Snubber Circuit:

Include protection features like overcurrent protection and a snubber circuit across the MOSFETs to mitigate switching losses and improve efficiency.

Considerations:

When designing the synchronous buck converter circuit using UCC27710DR, consider the following key aspects:

- Gate Driver Performance: Ensure that UCC27710DR can provide sufficient gate drive voltage and current for the MOSFETs used in the application.

- Bootstrap Capacitor Sizing: Select an appropriate value for the Bootstrap capacitor to ensure proper gate drive voltage during the switching transitions.

- Layout and Grounding: Pay attention to PCB layout and grounding techniques to minimize parasitic inductance and optimize switching performance.

- Thermal Management: Provide adequate heatsinking for UCC27710DR and MOSFETs to dissipate heat generated during operation and ensure reliability.

- EMI/EMC Considerations: Employ filtering components and proper layout practices to mitigate electromagnetic interference and ensure compliance with regulatory standards.
