Part Number: LM25066A Tool/software: Hi Team,
Could you pls help with the questions from customer below?
If the output capacitance is huge, say 20000uF or more; what would be the best approach to limit the inrush and at the same time reduce the SOA concern…
Hi John,
The output capacitors discharge through the short-circuit current during the output hot-short. Capacitors won't discharge through the 190-mA pull-down GATE current. 190-mA gate pull-down current activates only for a short while (~ 10 μs).…
Part Number: LM25066A After initial power-on, I am reading a false positive IIN_OC/PFET_OP_FAULT bit in the READ_DIAGNOSTIC_WORD.
Now I'm writing a CLEAR_FAULTS to clear the bit before I read the READ_DIAGNOSTIC_WORD, but I still see the false positive…
Part Number: LM25066A Other Parts Discussed in Thread: LM25066 , I am not able to understand intended meaning of statement "The LM25066 will pull the SMBA pin low after the input voltage has exceeded its POR threshold to indicate that the volatile memory and…
Part Number: LM25066A For first bring up, I must implement SMB bus for operation or it's enough to connect UVLO/OVLO and the peripheral components according to EVL that the gate FET will open and I will have 12V?
Part Number: LM25066A Other Parts Discussed in Thread: TPS25990 , LM25066 We are planning to use the LM25066A in our design. We have selected primary components based on the design calculation sheet provided in the TI sheet and training videos. I am attaching…
Part Number: LM25066A Other Parts Discussed in Thread: LM25066 Greetings. My team and I have two questions regarindg IC LM25066APSQ/NOPB.
1) Regarding the DIODE pin. I see on the datasheet that it can be expected to have an accuracy to within 2 degrees…
Yes, there is a possibility for the LM25066A to falsely latch a IIN_OC/PFET_OP_FAULT bit at start-up. This is the reason to send the CLEAR_FAULTS command.
