RAC20-12SN Frequently Asked Questions (FAQs)

  • The recommended PCB layout for optimal thermal performance involves placing the module on a multi-layer PCB with a large copper area for heat dissipation. The copper area should be connected to a solid ground plane to ensure good heat conduction.
  • To ensure reliable start-up of the converter, make sure to provide a slow and controlled input voltage ramp-up (dv/dt < 50mV/μs) and ensure that the input voltage reaches the minimum specified voltage (12V) before the converter is enabled.
  • The maximum allowed capacitance on the output is 220μF. Exceeding this value may cause instability or oscillations in the converter.
  • While the RAC20-12SN is rated for operation up to 80°C, it's essential to consider the derating curves and thermal management to ensure reliable operation in high-temperature environments.
  • To protect the converter from input voltage surges or spikes, consider adding a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input to limit the voltage to within the specified range.
