EMH4T2R Frequently Asked Questions (FAQs)

  • ROHM recommends a 4-layer PCB with a solid ground plane and a separate power plane for the EMH4T2R. The device should be placed near the power source, and the input and output traces should be kept short and away from noise sources.
  • To ensure stability, ROHM recommends using a minimum output capacitance of 10uF, and a maximum equivalent series resistance (ESR) of 1 ohm. Additionally, the output voltage should be decoupled with a 1uF ceramic capacitor.
  • Although the datasheet specifies a maximum input voltage of 5.5V, ROHM recommends limiting the input voltage to 5V to ensure reliable operation and to prevent damage to the device.
  • Yes, EMH4T2R is rated for operation up to 125°C. However, ROHM recommends derating the output current and voltage at high temperatures to ensure reliable operation and to prevent thermal shutdown.
  • ROHM recommends checking the input voltage, output current, and PCB layout for any issues. Additionally, using an oscilloscope to monitor the output voltage and current can help identify any instability or noise issues.
