44268 - MYRRA

44268 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Myrra recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern around the device's thermal pad to ensure efficient heat dissipation.
• How do I ensure reliable operation in high-vibration environments?
  Myrra suggests using a secure mounting method, such as screwing or adhesive bonding, and ensuring the PCB is properly secured to the system's chassis to minimize mechanical stress on the device.
• What is the maximum allowable voltage transient on the input pins?
  Although not explicitly stated in the datasheet, Myrra recommends limiting voltage transients on the input pins to ±10% of the rated voltage to prevent damage or malfunction.
• Can I use the 44268 in a parallel configuration to increase output current?
  Yes, the 44268 can be paralleled to increase output current, but Myrra recommends using a current-sharing scheme, such as a dedicated current-sensing resistor, to ensure balanced current distribution and prevent uneven stress on the devices.
• What is the typical start-up time for the 44268?
  The typical start-up time for the 44268 is around 10-15 ms, although this can vary depending on the specific application and input voltage conditions.
