Part Number: UCD7138 Tool/software: Hi Team,
Customer ask that whether UCD7138 has next Gen? The VCC is not enough for SiC MOS and VD is not enough for 48V server PSU. The competitor is like NCP4306. Please feel free to contact me, thanks.
BRs,

Part Number: UCD7138 Tool/software: Hi all,
I have been researching the LLC SR driver. I've read the datasheet of UCD7138, and I have a question.
In "8.2 Functional Block Diagram (P.11)", there is an OR gate. It ORs the Q and comparator output,…

Hello,
I am working on LLC converter design where UCD7138DRST is used as gate driver for synchronous MOSFETs (two in parallel).
I have disabled DTC input and also grounded the CTRL pin externally so PWM output is in line with input…
Part Number: UCD7138 Tool/software: Hello, would it be possible to get a SPICE model for the UCD7138 that is usable in KiCAD's integrated NGSpice? The published, encrypted PSpice model doesn't work.
I am trying to drive a GaN HEMT with this driver…
Part Number: UCD7138 Dear Sir,
I want to use UCD7138 for my application which has MOSFET VDS as 150V max ( IPP076N15N5AKSA1 ).
Can i use this driver W/O VD pin ?
If not , can you please suggest alternate PN for 150V bus volt?
Part Number: UCD7138 I want to use UCD7138 in 400V Mos drive，I use a 650V low current MOS to block VD，but this MOS‘s turn off time longer than main MOS turn on time，whether this will destroy UCD7138？If yes，How can I use ucd7138 in this condition…
Hello Yukiooyama,
Thanks for waiting. After discussing with others, I believe the code in the UCDA LLC firmware has a typo. The correct code should have DTC_MODE = 2. Both the phase A and phase B should be enabled. Thank you for bringing this to our attention…
Part Number: UCD7138 Other Parts Discussed in Thread: UCD3138A As for TI's UCD7138 chip, I have the following questions:
1. CTRL pin is defined in the manual as: whether to enable rising edge optimization, but if CTRL is pulled down in the application…
Part Number: UCD7138 Hi UCD experts,
The UCD7138 VD pin is connected to the diode conduction detection comparators internally.
My question is what would happen if this pin is somehow floating?
Does UCD7138 still work normally?
Thanks,
Part Number: UCD7138 Other Parts Discussed in Thread: UCD3138 Hello, I am currently studying the SR behavior of PSFB.
I wonder if the PSFB converter can not use the same controller as the UCD7138.
Even though it is not an LLC converter, the PSFB has a…
