  • Using LMZ31710 for Higher Output Voltages
    PDF, 95 Kb, Datei veröffentlicht: Nov 9, 2015
    The LMZ31710 power module has been designed and characterized for operation at output voltages from0.6 V to 5.5 V. However, several applications require higher voltages than the standard point-of-loadvoltages that the LMZ31710 is designed for. Following the guidance in this application note, theLMZ31710 can be used for output voltages up to 9.5 V. All data included in this application note h

    This thermal application report provides guidelines for the optimal board layout to achieve the best thermalresistance for exposed packages. The thermal resistance between junction-to-ambient (ОёJA) is highlydependent on the PCB (Printed Circuit Board) design factors. This becomes more critical for packageshaving very low thermal resistance between junction-to-case such as exposed pad TSSOP

    Electromagnetic Interference (EMI) is an unwanted effect between two electrical systems as a result ofeither electromagnetic radiation or electromagnetic conduction. EMI is the major adverse effect caused bythe application of switch-mode power supplies (SMPS). In switching power supplies EMI noise isunavoidable due to the switching actions of the semiconductor devices and resulting disconti
