VIPER50ASP-E datasheet by STMicroelectronics

VIPER50ASP-E Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure good thermal dissipation.
• How do I ensure reliable start-up of the VIPER50ASP-E?
  To ensure reliable start-up, ensure that the input voltage rises slowly (dv/dt < 50 mV/μs) and the output capacitor is properly sized to handle the inrush current.
• What is the maximum allowed voltage on the VCC pin?
  The maximum allowed voltage on the VCC pin is 15V, exceeding this voltage may damage the device.
• Can I use the VIPER50ASP-E in a high-temperature environment?
  Yes, the VIPER50ASP-E is rated for operation up to 150°C, but ensure that the device is properly derated for temperature and the PCB is designed to handle the thermal stress.
• How do I troubleshoot issues with the VIPER50ASP-E?
  Use an oscilloscope to monitor the input and output waveforms, and check for proper voltage levels, frequency, and duty cycle. Also, ensure that the PCB layout and component selection meet the recommended guidelines.
