PA89 Frequently Asked Questions (FAQs)

  • Apex Microtechnology recommends a 4-layer PCB with a thermal plane on the inner layer to dissipate heat. A heat sink or thermal pad is also recommended to ensure proper thermal management. Consult Apex's application note AN-114 for more details.
  • Use a voltage regulator or a voltage limiter to prevent overvoltage. For overcurrent protection, use a current sense resistor and a fuse or a current limiter. Additionally, ensure that the input and output capacitors are properly sized to prevent voltage spikes.
  • The PA89 is rated for operation from -40°C to 125°C. However, the device's performance and reliability may degrade above 100°C. Consult Apex's datasheet and application notes for more information on thermal derating.
  • Yes, the PA89 is designed to meet the requirements of high-reliability and aerospace applications. Apex Microtechnology offers a range of screening options, including burn-in and environmental testing, to ensure the device meets the required standards.
  • Consult Apex's application note AN-115 for troubleshooting guidelines. Common issues can be resolved by ensuring proper PCB layout, decoupling, and thermal management. Additionally, verify that the input and output impedances are properly matched.
