The more recent datasheet (2017) have the following values:
The data sheet from 2013 - SNVS610L –DECEMBER 2009–REVISED APRIL 2013 has the following compensation values:
For the 5th and 7th lines there are changes…
Part Number: LMZ10504 Other Parts Discussed in Thread: LMZ31704 , LM10504 , TPS25925 , TPD1E05U06 when i use the LMZ10504,this module often damaged,the ouput pin has shorted to ground,
the input voltage is 4.5 and the output is 3V3.
please see the schematic…
There is an additional parenthesis and a square term missing in the Rfbt equation #6. Please use the following equation while we are updating the application note:
Rfbt = Rcint * (1+fco/fLC)*Vin*sqrt(1+(fco/fesr)^2)/((sqrt((1+(fco/fLC)^2)^2+(fco/(Q*fLC…
Part Number: LMZ10504 The Design is implementing a LMZ10504TZX-ADJ Regulator. Vin is 5V and the Enable pin is pulled up to Vin with 7.5K ohm resistor.
When observing the Enable pin, it appears to be carrying a switching signal that dips -750mV and rises…
Other Parts Discussed in Thread: LMZ10504LMZ10504 data sheet recommends a ceramic input cap, 22 uF or 47 uF. The applicaiton requires the use of Mil-spec capacitors and this much capacitance in ceramic is very large.
Is a Tantalum capacitor acceptable…
Other Parts Discussed in Thread: LMZ10504 Hi,
I have a question about internal connection of the LMZ10504.
Is exposed pad connected to ground terminal internally? (My question is connection between exposed pad and ground terminal inside of thie device…
Hi,
So from my understanding on page 13 of the datasheet, when using this part you want the EN input to be either based off the input voltage or output voltage. There is no reason to have the EN pin turned on before the input to the IC.
My question:…
Other Parts Discussed in Thread: LMZ10504 Hello,
We are using the LMZ10504 module in application where the Output load capacitance can vary from 22uF to 220uF.
We need to ensure the stability of the module other all the output capacitance range, with…
Hi Giuseppe,
The LMZ10504 runs at 1 MHz switching frequency. The output ripple should be small. I've run a Webench design on the LMZ10504 and the output voltage peak-2-peak ripple is 8mV with one 220uF 15mOhm output capacitor. If further reduction is…
