Other Parts Discussed in Thread: LM10011
Hi Team,
My customer is designing a new project. We just penetrate our LMZ31520 to customers, but several questions need team's quick support to confirm:
1. Is the V5V pin(pin 61) output pin or input pin? From the datasheet's most description, it seems it is the output of the internal LDO, 5v output. However, in our datasheet's page 2, V5V is described as input, it's confused a lot and we can't find one confirmed descrption about this, can some expert can help on this? Because I also see our reference schematic connect POWER_UP to V5V, seems V5V is output pin.
2. If V5V pin is output pin and customer connect another 5V supply to this 5V5 pin, any risk for this? From datasheet page 2, it seems V5V is input pin and can accept up to 7V maximum non-damaged input voltage, need expert to help clarify this?
3. If our recommended mode for SS_SLE pin FCCM mode?
4. Can customer left POWER_UP pin float if they don't use it?
5. How to well design with LM10011 and LMZ31520 for our 66AK process's dynamic supply voltage, for example, if customer use a 2.195kohm pull down resistor on Vadj and then connect to LM10011's IDAC_OUT, do they need any more external circuit or filter circuit?
6. If possible, can you help share a reference schematic showing the parameters used for LM10011 and LMZ31520? Like how to choose the Rset of LM10011 and if these is power up sequence between LM10011 and LMZ31520, for example, if we enable LM10011 firstly then enable LMZ31520, any risk for this?
7. Below is customer's schematic, can expert help check it after review above questions:
Thanks a lot for support this important DIN.
Best regards,
Sulyn
