A good PCB layout for the UCC28070DW involves keeping the high-frequency switching nodes (e.g., SW and VIN) away from sensitive analog nodes, using a solid ground plane, and minimizing loop areas. TI provides a recommended layout in the datasheet and application notes.
The inductor value depends on the input voltage, output voltage, and desired switching frequency. A good starting point is to use the inductor selection guide in the datasheet or TI's Power Stage Designer tool. You can also use the following formula: L = (VIN - VOUT) / (ΔI * f_sw * VOUT), where ΔI is the desired inductor ripple current.
The maximum junction temperature (Tj) for the UCC28070DW is 150°C. It's essential to ensure that the device operates within this temperature range to prevent damage and ensure reliability.
The UCC28070DW has a built-in OCP feature. You can set the OCP threshold by connecting a resistor (R_OCP) between the OCP pin and GND. The OCP threshold voltage is 0.5V, and the resistor value can be calculated using the formula: R_OCP = 0.5V / (I_OCP * 0.01), where I_OCP is the desired overcurrent threshold.
Yes, the UCC28070DW can be used in a synchronous rectification topology. However, you'll need to add an external FET driver and ensure that the FETs are properly synchronized with the UCC28070DW's switching frequency. TI provides application notes and reference designs for synchronous rectification topologies.
