Myrra 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 efficient heat dissipation.
Myrra suggests using a secure mounting method, such as screwing or adhesive, and ensuring the device is properly soldered to the PCB. Additionally, consider using a vibration-dampening material, like a silicone gel, to reduce mechanical stress.
Although the datasheet specifies a maximum input voltage, Myrra recommends limiting voltage transients to ±10% of the nominal input voltage to prevent damage to the internal components.
Yes, the 44266 can be paralleled to increase output current, but Myrra recommends using a current-sharing scheme, such as a dedicated current-sensing resistor, to ensure equal current distribution and prevent uneven stress on the devices.
Myrra suggests checking for soldering issues, ensuring proper input voltage and current, and verifying the PCB layout for thermal and electrical integrity. Additionally, using a logic analyzer or oscilloscope can help identify signal integrity issues or voltage transients that may be causing the fault.
