A symmetrical layout with a solid ground plane and minimal signal trace length is recommended. Keep the input and output traces separate and avoid crossing them to minimize noise and crosstalk.
Use a 10uF ceramic capacitor in parallel with a 100nF ceramic capacitor, both connected between the VIN pin and GND pin, as close to the PJ-004CH as possible.
The PJ-004CH can withstand up to 6V input voltage, but it's recommended to operate within the specified 3.3V to 5.5V range for optimal performance and reliability.
The PJ-004CH is rated for operation up to 85°C, but its performance may degrade above 70°C. Ensure proper heat dissipation and consider derating the output current at high temperatures.
Check the input voltage, output voltage, and output current. Verify the PCB layout and decoupling. Use an oscilloscope to check for noise and ripple. Consult the datasheet and application notes for troubleshooting guides.
