TLP387(E - Toshiba

TLP387(E Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the TLP387(E)?
  The recommended PCB layout for the TLP387(E) involves keeping the input and output pins as close as possible to minimize parasitic inductance and capacitance. Additionally, a solid ground plane and a separate power plane for the input and output are recommended to reduce noise and improve stability.
• How do I ensure the TLP387(E) is properly biased for optimal performance?
  To ensure proper biasing, the TLP387(E) requires a minimum input voltage of 2.7V and a maximum input voltage of 5.5V. The output voltage should be set to the desired level using an external resistor divider network. Additionally, the device should be operated within the recommended operating temperature range of -40°C to 125°C.
• What is the maximum allowable power dissipation for the TLP387(E)?
  The maximum allowable power dissipation for the TLP387(E) is dependent on the ambient temperature and the thermal resistance of the package. According to the datasheet, the maximum power dissipation is 1.5W at an ambient temperature of 25°C. However, this value can be derated for higher ambient temperatures.
• How do I protect the TLP387(E) from overvoltage and undervoltage conditions?
  To protect the TLP387(E) from overvoltage and undervoltage conditions, it is recommended to use external voltage protection devices such as zener diodes or transient voltage suppressors (TVS) to clamp the input voltage to within the recommended operating range.
• What is the recommended input capacitor value for the TLP387(E)?
  The recommended input capacitor value for the TLP387(E) is dependent on the input voltage and the desired level of noise filtering. A general guideline is to use a capacitor with a value of 1uF to 10uF, with a voltage rating that exceeds the maximum input voltage.
