MaxLinear provides a recommended PCB layout guide in their application note AN5151, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize EMI.
The XR31235ED has a programmable output voltage range, which can be configured using the VOUT_SEL pins. The specific configuration depends on the desired output voltage range, and the datasheet provides a table to determine the correct pin settings.
While the datasheet specifies a maximum input voltage of 5.5V, it's essential to note that the device can handle input voltage transients up to 6.5V for a short duration (typically 100ms). However, sustained operation above 5.5V is not recommended.
MaxLinear provides guidance on EMC compliance in their application note AN5152, which includes recommendations for PCB layout, component selection, and shielding to ensure the XR31235ED meets relevant EMC standards.
The thermal derating curve is not explicitly provided in the datasheet, but it can be obtained by contacting MaxLinear's technical support or through their online resources. The curve provides information on the device's power dissipation capabilities at different ambient temperatures.
