Hello Deepak,
The wattage of the resistors is low as the input impedance of the sense amplifier is relatively high, so the standard 1/8th W should be sufficient.
1uF for CBST should be ok.
The 2nF capacitor in parallel to the RC compensation network seems…
Hello Jacob,
Is it possible that the other board is running permanently in buck mode and this one is running in buck-boost mode?
If this is the case, please check the good configuration in buck-boost mode. If this is the case, this could point into the…
Part Number: LM5122 Hello,
can you please Please help to evaluate max output power capability on one LM5122:
input voltage range 7.0V-18V, output 24V, output power 240W+
can you help to evaluate above condition if customer can use only one LM5122?
Thanks…
Part Number: LM5122 Hello,
The datasheet specifies tON-MIN, but only typical value. How much is the maximum tON-MIN? Without knowing the maximum tON-MIN, how can users know if their circuits meet tON-MIN spec? Best regards, K.Hirano
Hi Bhargav,
BHARGAV ITALIA said: Here is the wave form with Ch1= SS Ch2 =Vcc Ch3 =LO Ch3=HO
The noise pulse only appears on the first one or two startup attempts
I want to know what is the reference of HO? HO-SW or HO-AGND?
Please share SS, HO-SW, LO…
Part Number: LM5122 Hello,
I need help with a LM5122 based schematic.
I am desigining a 12v to 24v 240w boost converter. The schematic generated by the webench tool specifies Mosfets M1 and M2 are 2 qty each. How are these arranged?. I am familiar with…

Hi Cedrick,
For 5V VCC I guess you could put the average of the values you suggested here: TLO_OFF=575ns max (400+750/2).

Hi Brigitte,
I have recorded all the suggestions in my notes, and I will be designing a new PCB shortly. Therefore, you can close this thread.
I sincerely appreciate all the opinions and suggestions from the TI team, especially from Niklas. Thank you…
Hi Cedrick,
Sorry for the delay. I have no data on values between 4.5V and 5.5V VCC, and I cannot confirm that the max TLO_OFF time rises linear within this range. In addition, the 400ns and 750ns are the worst case maximum values, which are higher than…
