The recommended input capacitor value is 10uF to 22uF, with a voltage rating of 25V or higher, to ensure stable operation and minimize noise.
The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific application requirements.
The maximum ambient temperature for the UC3867DW is 70°C, but it can be derated to 50°C for high-reliability applications.
Yes, the UC3867DW can handle high currents, but it's essential to ensure proper thermal management, such as using a heat sink, to prevent overheating.
Check the PCB layout, ensure proper decoupling, and verify that the input and output capacitors meet the recommended values. Also, check for any noise or interference from other components or systems.
