Part Number: LM61440-Q1 Other Parts Discussed in Thread: LM61440 I'm trying to create BUCK regulator using TI LM61440 with the next input
Input voltage 9 -16V
Case 1:
output : 5V@2A
At 2MHz switching frequency it works
When I'm trying to reduce the…
Part Number: TPS61378-Q1 Hello Team,
My customer is trying to calculate compensation for the tps61378 and had a question about the internal feedback resistors on Spielberg.
For the fixed 5V output, what should we use in the quickstart calculator as Rup…
Hi Gareth,
Please use the LM25141-Q1 quickstart calculator to check your design. Here are some comments on the schematic:
4.7uH seems a bit high for a 2MHz design (check recommended value in the quickstart file based on the 15mOhm shunt).
Set LOL gate…
hi Zack,
Customer uses TPS61178 EVM and change the IC to TPS611781.
also change the Vout to 5V and fsw to 2MHz. they just follow it as simulation schematic.
The same issue happens on their board.
BR,
frank

Part Number: LMR61428 I'm an old-school developer with mostly linear-regulator experience and am looking for tips on picking the right 'boost' switching regulator for a specific project. It needs to take +5V in, either from a wall-wart or a battery, and…
Part Number: ADS1284 We are currently evaluating the ADS1284. We felt that the output stability of the ADC was higher than expected, so we enabled the Internal Short feature. However, the output stability of the ADC did not improve. Please give me some advice…
Other Parts Discussed in Thread: SN74LVC2G34 Hi Team,
We would like to ask your help regarding the customer's inquiry below.
We have a product that must plug into a legacy bus system that has long clock lines for timing. We are experiencing undershoot…
Part Number: LM61495-Q1 Other Parts Discussed in Thread: LM61495 Hi. Teams
I would like to apply LM61495QRPHT-Q1 to the project. I am trying to configure the circuit as below, but I have some questions.
- INPUT : 12V (Input range : 4V ~ 36V)
- Switching…
Hello Josef,
Yes you are correct, LMR23610 cannot be configured with 2MHz in Webench because it is only a 400kHz device.
The LMR23610-Q1 however is capable of switching at 2.2MHz, but not with Vin=5.7V and Vout=5V because this would violate the minimum…
Hi Kai, thank you for the detailed analysis. The 220pF capacitor did not helped. My source resistance is 600Ohm (series resistor to AHC04 gate output)
The AHC04 is only a reference/calibaration signal. I tr to send scope waveform. My TLE is working from…
