Application Notes

  • Using LMZ31710 for Higher Output Voltages
    PDF, 95 Kb, File published: 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
  • LMZ31710, LMZ31707, LMZ31704 Parallel
    PDF, 217 Kb, File published: Jul 2, 2013
    The LMZ31710 is a 2.95-V to 17-V input, 10-A output, integrated power solution which integrates the PWM controller, power MOSFETs, inductor and passives in a low-profile, QFN package. For applications requiring greater than 10 A, it is possible to parallel up to six LMZ31710 devices by following the recommendations in this paper.

    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
