L9660 Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the L9660 application note (AN4393) which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
  • The L9660 can be configured for different input voltage ranges by selecting the appropriate resistors for the voltage sensing circuit and adjusting the voltage regulation loop. The datasheet provides a table with recommended resistor values for different input voltage ranges, and the application note (AN4393) provides more detailed information on how to configure the device.
  • The maximum output current capability of the L9660 is dependent on the specific application and the thermal management of the device. The datasheet specifies a maximum output current of 3.5A, but this can be limited by the device's thermal performance. The application note (AN4393) provides guidance on how to calculate the maximum output current based on the device's thermal performance and the application's requirements.
  • The L9660 has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCP pin and the GND pin. The value of the resistor determines the overcurrent threshold. The datasheet provides more information on how to implement overcurrent protection, and the application note (AN4393) provides an example circuit and calculation for selecting the resistor value.
  • The EN (enable) pin on the L9660 is used to enable or disable the device. When the EN pin is high, the device is enabled and operates normally. When the EN pin is low, the device is disabled and enters a low-power standby mode. The EN pin can be used to implement power sequencing or to turn off the device when it is not needed, reducing power consumption.
