Part Number: LM5114 Other Parts Discussed in Thread: UCC27511A , UCC27511 Hello guys,
One of my customers is planning to replace UCC27511A with LM5114. At this moment, they have the following questions. Could you please give me your reply for them?…
Hi Peter,
Most everything looks in place for the design specs you've described. The only comment might be about the use of the UCC27511 gate driver ICs. Each of the drivers you have shown only has 0.1uF on VDD but you are driving parallel MOSFETs that…
Part Number: UCC2897A Other Parts Discussed in Thread: UCC27511 , PMP3162 My customer refers to the PMP3162 line, but when it happens to be transient (full load drops to no load), UCC27511 will die (U6 PIN6), how to deal with this problem, Thanks.
Part Number: UCC27714 Other Parts Discussed in Thread: UCC28180 , UCC27511 , , UCC27614 , UCC27511A Dear Ti Team,
De are working on 750W charger for 2-wheeler application and we are using few Texas instruments active parts i.e. UCC27714DR, UCC27511…
1) With either the BQ76920 or the BQ77905 does it list the driver current capability on the data sheets? I can't seem to find that. the UCC27511 list as 4A Peak.
2) The CHG driver goes to high impedance when off, thus relying on the 1M pull down resistor…
Hello David,
FOr >1MHz switching frequencies and depending on gate drive voltage from your application, you might consider LMG1020 and or UCC27611.
As for an alternative for UCC37322D, UCC27511 and/or UCC27517 might be good candidates given the low…
Part Number: PMP11237 Other Parts Discussed in Thread: UCC27511 , UCC27512 , UCC27710 , TLV760 Hello Sir,
I have several Queries.
1. Can I use IC no. UCC27512MDRSTEP instead of UCC27511DBVR? If so, what will be the output resistor's value instead…

Hello,
IN addition to Wei's comments, depending on your MOSFETs gate charge, gate drive range and dv/dt requirements, you may use a dual-ch driver like UCC27524 or use 2 single-ch drivers like UCC27511, UCC27517 to driver the FETs.
2 single ch IC…
