  RE: LM5102: LM5102MM power dissipation reducing

  Hello Gleb, I noticed that the gate charge of the MOSFETs is 78nC with two on each driver for a total of 156nC. The total gate drive power is Qg x VDD x fsw so if the switching frequency is high the gate drive power may be a consideration. For your...

  RE: LM5041: HD and LD waveform will have both high for 2ns

  Hi Howard, The LM5041 does not have any deadtime between the two outputs as one output is a simple inversion of the other. The LM5102 is a 100V gate driver with 1.6A/1.8A gate drive capability and adjustable dead-time. Do we know why the customer...

  RE: LM5041EVAL: Dead-time adjustment Buck Stage

  Dear Johny, LM5101 or LM5102 is recommend to co-work with LM5041 for buck gate driver which can program delay time. You can refer to LM5041EVAL reference design. Thanks

  RE: Question about UCC27210 behavior.

  Hello Go, I am an applications engineer at TI and will look to answer your questions. As was mentioned with previous responses, the UCC27210 does not have the feature we call input interlock which prevents both outputs from being high. TI does have...

  RE: LM5106: need upgrade device of this part

  Hi Howard, thanks for reaching out! Im on gate drivers apps team and will help out. Driver peak current does not determine gate driver power dissipation. (2.8A is the instantaneous peak current for only 100ns.) Gate drive power dissipation calculation...

  LM5102 delay

  Team, Can you help with the below question? "Would you be able to find out if the RT1 or RT2 pins were grounded, would this eliminate the turn on delay of the high side or low side gate drive signal from outputting high? Also, say if the high...

  LM5105 with 50ns dead time

  Hi my customer wants to reach 50ns dead time on LM5105 / LM5102. our D/S says that deadtime can be adjusted from 100ns to 600ns which seems to tell that 50ns is not achievable BUT it also says that one can use 5kOhm RDT, which implies deadtime...
