SRK1000ATR Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the application note AN5323, which includes guidelines for component placement, routing, and thermal management.
  • To optimize thermal performance, ensure good thermal coupling between the device and the PCB, use a thermal pad or heat sink, and follow the recommended PCB layout guidelines. Additionally, reduce the thermal resistance by using thermal vias and thermal layers.
  • The maximum allowed voltage on the VIN pin is 36V, but it's recommended to keep it below 30V to ensure reliable operation and to prevent damage to the internal voltage regulator.
  • To configure the SRK1000ATR for low-power mode, set the EN pin low, and ensure that the VIN pin is below the undervoltage lockout threshold. Additionally, reduce the switching frequency and adjust the output voltage to minimize power consumption.
  • The recommended input capacitor value is 10uF to 22uF, with an ESR of less than 100mΩ. A larger capacitor value can be used, but it may affect the startup time and stability of the device.
