There are many consideration for a SMPS in an automotive application.
1) Operating temperature range
2) Drop-out voltage during engine cranking
3) Maximum input voltage in the likely event of load dump. (Is a 28V rated device enough?)
4) Is input…
Part Number: LM5161-Q1 Other Parts Discussed in Thread: LM53635-Q1 , LM5018 , LM25141-Q1 , LM53603-Q1 Hi,
We got a question from the customer about LM5161-Q1. Could you help us?
[Question] According to the datasheet, the operating lifetime is de-rated…
Other Parts Discussed in Thread: LM53603 Hi,
Mycustomer has three questions about [9.2.2.6 BIAS] of LM53603 datasheet. =======================================================
Q1. Is it possible to Vout is BIAScurrent any 3.3V or 5V is below 100mA…
Other Parts Discussed in Thread: TIDA-00699 , LM53603 Hello team,
Hope you are well.
Would you be able to help out with customer inquiry:
Does the TIDA-00699 operate through (5V buck output doesn’t fall out of regulation) ISO 7637-2:2004 Pulse 1…
Brian,
As Howard suggested, the buck converter topology might be a good fit for this application as well. The only spec that may be difficult to meet is the achieving 5V, 3A at Vin=5.5V. You need a part that offers low-dropout in order to meet this…
Hi Sergio,
Because the LM26003 is a non synchronous device it doesn't have what I would call a true Forced PWM operation as the inductor current can never go negative because of the external catch diode. The FPWM mode on the 26003 basically disables…
Ryuji,
1) The LM75610 is compatible with ISO7637-2, 2011.
2) Pulses 4, 5a, 5b have been moved out of ISO7637-2 (2004) and are now in ISO 16750-2 and ISO21848 per the note on pg 16 of ISO7637-2 (2011). I looked over several TIDA ref designs and could…
Ciao, Allesandro,
Please find attached a presentation that was held on a recent TI-TechDay, which covers your topics.
It contains guidelines on what to do for sensitive circuits to prevent BCI issues (or really any external RF or transient). Slide…
