Hello,
when EN low is at ADM1270, is the internal LDO and thus VCAP active?
I ca not find any info from functional block digram and the text in the datasheet.
Thanks for any help.
Hello,
I need IBIS Model for the following part numbers, in order to perform SI Analysis
1. ADM1270ARQZ
2. ADR440BRZ-REEL7
3. ADG721BRMZ-REEL
When entering 19V, ADM1270 occurs in the following three conditions.
ADM1270 => IC Burned (Burned after power on)
ADM1270 => IC Hot (Ic started hot)
ADM1270 => (Vcc=19V, Vcap no output.)
Is there a problem with the design?
Hi,
We are planning to design a 28V fixed power supply with adjustable current limit setting using ISET pin of ADM1270 IC in discrete steps,need to know information on how stable the device will perform,during change over from one discrete current limit…
I'm using ADM1275 in my designs and I have simulated some of them in Simetrix. Now I need a high voltage version and I'm looking at ADM1270. The controlled voltage is in the range 4-60V, so I'd like to simulate some scenarios first. Is there any chance…
ADM1270. Is there are any restrictions to use this controller in N+1 power redundancy?
In datasheet I found no details about pull-up pull-down mechanics in gate control of Q1 & Q2.
Only found such parts:
