I have shared you schematic, layout and scope measurements to your mail id (firstname.lastname@example.org) please go through that and help me to solve spurious problem.
I requested a footprint of ADP1707ACPZ-1.8-R7 from the request form.I waited. But I don't get a footprint yet.How should I do to get a footprint of ADP1707ACPZ-1.8-R7?
Give my best regards.
A circuit diagram was designed using LTspice, as shown in the attached picture.When the voltage on the TK/SS pin changes, so does the output voltage.Can you explain what the problem is?The circuit diagram did not observe the reference,Is there…
I want to use the LT1763IS8-1.8 chip to convert +5V to 1.8V. The schematic and PCB are as follows, but in the actual circuit, the output of the 1-pin is measured by a multimeter to be 2.1V, and the +5V input is also reduced to 4.5V. Why, what should…
Hello everybody, I have been making the schematic for my own 1701 board (yay yay). But since I am not an engineer I am awfully afraid of making any mistake. So I chose BC857 as a 1.8 regulator transistor since it is small and has a huge beta. It seems…
Is it possible that the 3.3 is feeding back into the 1.8v rail before the 1.8V becomes active?
1) I would tie a schottkey diode from 1.8 to 3.3 to make sure the 1.8 never really exceeds the 3.3 rail
2) is it possible the 1.8 comes up before your 3.3…
VDD_IO is an Input/Output Digital Power Supply (1.8 V or 3.3 V), that's clear. But how can I SPECIFICALLY select VDD_IO to work in 1.8 V.
Vdet and Vref pin voltages typically vary between -1.8 to +1.8 V.
Measure your voltage from GND to DVDD (1.8V) on your TB1 component.
I got the same error if this does not get any power.
Then measure the capacitors C54 and C56, these should be receiving the 1.8 Volts if they are connected.
The DVDD 1.8 Volts did…
