LTC2975 is powered at 12V (pin VPWR). VOUT_EN pins of the LTC2975 are connected to RUN pins of LTM4644.
Do the VOUT_EN pins have to be pulled up to 3.3V (pin VDD33) with EXTERNAL resistors? The design checklist on p.103 of the LTC2975 data sheet implies…
The QFN version of the part has a VDD33(IN) (pin 12) that feeds the internal 2.5V regulator. This pin does not exist in the BGA version. Does the BGA version connect the output of the internal 3.3V regulator to the 2.5V regulator internally?
Hello
I'm designing a new system. I would like to use a PowerManager.
I need to control the current and voltage of 4 supplies.
Now I have seen, that I could use a LTC2977. It allows to use the odd channels to be configured as current sens. This would…
Thanks for taking the time to answer my questions about the DC2428 demo board set you designed. I am basically copying it for my design. I have a few more questions. Please answer at your convenience.
I noticed you used a diode-connected transistor (Q1…
Hi Alex,
That's correct, the LTC2972 does not have OCP support. The device is a simpler version of the LTC2975. I don't have any insight into future devices. If you need to add OC supervision, you could use a current sense amp and tie its output…
Hi MPETER,
I scan through the GitHub and Linduino site and they contain many useful software tool support for programming the LTC2975 for our software engineer. They can use these information to design the programming application require to communicate…
Hi Dave,
Sorry for the delay. Because this also involves the LTC2975 I will contact you at your email now, and bring in the supporting engineer for the LTC2975 who also generated the DC2363A. Noted routing for this can also be tricky to avoid noise coupling…
just looking for someone to look over my circuit to make sure i've hooked everything up ok. used most of the circuitry from DC2363A but find this circuit diagram a little confusing around the sense lines to the LTC2975 device.
