v c / ? t, where ? v=25v c=5000pf & ? t=25ns, we can determine that to charge 5000pf to 25 volts in 25ns will take a constant current of 5a. (in reality, the charging current won?t be constant, and will peak somewhere around 8a). supply bypassing in order for our design to turn the load on properly, the ixd_514 must be able to draw this 5a of current from the power supply in the 25ns. this means that there must be very low impedance between the driver and the power supply. the most common method of achieving this low impedance is to bypass the power supply at the driver with a capacitance value that is an order of magnitude larger than the load capacitance. usually, this would be achieved by placing two different types of bypassing capacitors, with complementary impedance curves, very close to the driver itself. (these capacitors should be carefully selected and should have low inductance, low resistance and high-pulse current-service ratings). lead lengths may radiate at high frequency due to inductance, so care should be taken to keep the lengths of the leads between these bypass capacitors and the ixd_514 to an absolute minimum. grounding in order for the design to turn the load off properly, the ixd_514 must be able to drain this 5a of current into an adequate grounding system. there are three paths for returning current that need to be considered: path #1 is between the ixd_514 and its load. path #2 is between the ixd_514 and its power supply. path #3 is between the ixd_514 and whatever logic is driving it. all three of these paths should be as low in resistance and inductance as possible, and thus as short as practical. in addition, every effort should be made to keep these three ground paths distinctly separate. otherwise, the returning ground current from the load may develop a voltage that would have a detrimental effect on the logic line driving the ixd_514. output lead inductance of equal importance to supply bypassing and grounding are issues related to the output lead inductance. every effort should be made to keep the leads between the driver and its load as short and wide as possible. if the driver must be placed farther than 2? (5mm) from the load, then the output leads should be treated as transmission lines. in this case, a twisted- pair should be considered, and the return line of each twisted pair should be placed as close as possible to the ground pin of the driver, and connected directly to the ground terminal of the load. supply bypassing, grounding practices and output lead inductance note: solder tabs on bottoms of dfn packages are grounded 8 pin dip (pi) 8 pin soic (sia) vcc in nc gnd vcc out out 1 2 3 4 8 7 6 5 i x d i 5 1 4 gnd 8 pin dip (pi) 8 pin soic (sia) vcc in nc gnd vcc out out 1 2 3 4 8 7 6 5 i x d n 5 1 4 gnd 6 lead dfn (d1) (bottom view) in n/c gnd vcc gnd out 1 2 3 6 5 4 i x d n 5 1 4 6 lead dfn (d1) (bottom view) in n/c gnd vcc gnd out 1 2 3 6 5 4 i x d i 5 1 4 12 copyright ? 2006 ixys corporation all rights reserved ixdi514 / ixdn514 ixys semiconductor gmbh edisonstrasse15 ; d-68623; lampertheim tel: +49-6206-503-0; fax: +49-6206-503627 e-mail: marcom@ixys.de ixys corporation 3540 bassett st; santa clara, ca 95054 tel: 408-982-0700; fax: 408-496-0670 e-mail: sales@ixys.net www.ixys.com h e e a a1 b d d c l h x 45 h h l e e b c m n m n e1 e ea l eb e d d1 c b3 b2 b a2 0.018 [0.47] 0 . 0 2 0 [ 0 . 5 1 ] 0 . 0 1 9 [ 0 . 4 9 ] 0 . 0 3 9 [ 1 . 0 0 ] 0 . 1 5 7 0 . 0 0 5 [ 3 . 9 9 0 . 1 3 ] 0.1970.005 [5.000.13] 0 . 1 2 0 [ 3 . 0 5 ] 0.100 [2.54] 0.137 [3.48] s0.002^0.000; o s0.05^0.00;o [] 0.035 [0.90] preliminary technical information the product presented herein is under development. the technical specifications offered are derived from data gathered during objective characterizations of preliminary engineering lots; but also may yet contain some information supplied during a pre-production design evaluation. ixys reserves the right to change limits, test conditions, and dimensions without notice. |
