Zedboard Power Supply Voltage Tolerance

Question

Hello, What is the voltage range tolerance on the 12 V power supply input to the Zedboard? Does it need to be a consistent 12 V, or can it be over a range?

Hello Mobis, The power supplies we ship do not have a tolerance listed on the label. The units we have (I.T.E. and L.T.E.) are assumed to be within +/-5% over the entire load and current range as rated from the tip. FYI: The input to the PCIe and IOCC can vary from 11.2 to 14V. For all practical purposes, the PMICs will turn off when VIN drops below 9.0V for greater than 10mS. They will not turn back on until the VIN reaches 11.0V. This hysteresis is included to allow high demand transients without tripping the PMICs into the off state. --Josh
