LM36922HYFFR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the LM36922 evaluation module documentation, which includes a thermal pad and vias for heat dissipation. Following this layout can help achieve optimal thermal performance.
  • To ensure stable output voltage regulation, it's essential to follow the recommended input and output capacitor selection, as well as the suggested PCB layout. Additionally, make sure to decouple the input voltage with a suitable capacitor and use a low-ESR output capacitor.
  • Although the datasheet specifies a maximum input voltage of 42V, it's recommended to limit the input voltage to 40V to ensure reliable operation and prevent damage to the device.
  • The LM36922 is rated for operation up to 125°C, but it's essential to consider the device's power dissipation and thermal management when operating in high-temperature environments. Ensure proper heat sinking and follow the recommended thermal design guidelines.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where Iout is the output current, ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
