we have designed a supply system for a FPGA with the LTM4620A power module, for generating a output reference of 0.95V / 26A with the parallel mode (both outputs are tied together) from a 12V input source. The circuit is showed in the image below…
LTM4620A : 5V ==> 4V@26A
I want to know about input supply current of LTM4620A for singe 26A ouput.
In datasheet, input supply current is
S(VIN) Input Supply Current VIN = 5V, VOUT = 1.5V, IOUT = 13A ==> 4.6A (typ)
VIN = 12V…
The minimum of 4.5V Vin is valid when using INTVcc. The use of EXTVcc is mainly for improving the efficiency. Please do not exceed 6V on INTVcc and EXTVcc pins. In addition, please keep in mind that the maximum duty cycle for this device is 95…
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…
Is it possible to connect J6 (TEMP) to GND or leave it floating? Should be ok, if it is just connected to a (PNP) diode internally, but all of the examples use a resistor to Vin to set an appropriate current, despite the temperature measurement never…
We are using above circuit for 5V/25A.
Above circuit is it working ? or any changes require?
can you give me feedback
Hello I am so glad that now also linear is part of Analog Devices and I can ask my question in this good community.
In our custom board we used LTM4620A for 3.8V and 2.3V output. both output voltages are good without any problem. Power Good of channel…
Hello Analog experts,
I used LTM4620A in my last design but now I want to use LTM4676A because it has wider input voltage range. Output voltage of LTM4676A can be set either with PMBUS or by PIN Strapping. I want to use PIN Strapping for setting the…
It is recommended to arrange the two close output voltage channels at one LTM4620A module.
The frequency setting does not directly affect the output voltage regulation. But care needs to make to ensure
1) Frequency selection ensure Ton…
