A good PCB layout for the UCC35702N involves keeping the input and output stages separate, using a star-ground configuration, and placing the input filter components close to the IC. Additionally, using a solid ground plane and minimizing trace lengths can help reduce EMI.
The choice of input filter components depends on the specific application requirements, such as input voltage, frequency, and desired attenuation. A good starting point is to use the recommended component values in the datasheet, and then adjust based on simulation and measurement results.
The UCC35702N can deliver up to 2A of output current, but this depends on the input voltage, output voltage, and thermal conditions. It's essential to check the datasheet and perform thermal calculations to ensure the device can deliver the required output current.
The UCC35702N has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The resistor values can be calculated based on the desired overcurrent threshold and the output voltage.
The EN (enable) pin is used to turn the device on and off. When the EN pin is high, the device is enabled, and when it's low, the device is disabled. This pin can be used to implement power sequencing or to turn off the device during shutdown or standby modes.
