XL0840-TR Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended layout and PCB design guide in their application note AN4965, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The output capacitor selection depends on the specific application requirements, such as output voltage, current, and ripple. A general guideline is to use a low-ESR capacitor with a value between 10uF to 100uF, and a voltage rating at least 1.5 times the output voltage. Consult the datasheet and application notes for more specific guidance.
  • Although the datasheet specifies a maximum input voltage of 42V, it's recommended to derate the input voltage to 36V to ensure reliable operation and prevent damage to the device. Consult the datasheet and application notes for more information on input voltage derating.
  • The XL0840-TR 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. Consult the datasheet and application notes for more information on implementing overcurrent protection.
  • The thermal resistance of the XL0840-TR package (QFN24) is typically around 30°C/W (junction-to-ambient) and 10°C/W (junction-to-case). This information is usually provided in the datasheet or the package thermal characteristics document.
