L9758TR Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the application note AN4391, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • The input capacitor selection depends on the input voltage, ripple current, and ESR requirements. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the maximum input voltage, and an ESR of less than 1 ohm. STMicroelectronics recommends using a ceramic capacitor with an X7R or X5R dielectric.
  • The maximum allowed voltage drop across the sense resistors is 100 mV. Exceeding this voltage drop may affect the accuracy of the current sensing and potentially lead to overcurrent protection issues.
  • The L9758TR is rated for operation up to 150°C, but it's essential to consider the derating of the device's performance and reliability at high temperatures. Consult the datasheet and application notes for guidance on thermal management and derating factors.
  • The L9758TR has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold is set by the voltage divider ratio, and the device will shut down if the input voltage exceeds the set threshold.
