Texas Instruments recommends a compact layout with short traces, and placing the IC close to the power stage. Additionally, a solid ground plane and a separate analog ground plane can help reduce noise and EMI. Refer to the application note SLUA271 for more details.
The choice of external components depends on the specific application requirements. For the voltage reference, a 2.5V or 3.3V reference is recommended. For the current sense resistors, the value depends on the maximum current and the desired accuracy. Refer to the datasheet and application notes for more information.
The UCC3808AD-1G4 has an operating temperature range of -40°C to 125°C. However, the device can be operated up to 150°C with derating. Refer to the datasheet for more information on thermal derating.
The UCC3808AD-1G4 has a built-in overcurrent protection feature. The OCP pin can be connected to a resistor and capacitor to set the overcurrent threshold and response time. Refer to the datasheet and application notes for more information on implementing overcurrent protection.
The recommended input voltage range for the UCC3808AD-1G4 is 8.5V to 14V. However, the device can operate up to 16V with reduced performance. Refer to the datasheet for more information on input voltage range and performance.
