Part Number: VOLT-DIVIDER-CALC It is hard to believe that a design aid as poor as "VOLT-DIVIDER-CALC" should exist on TI's otherwise excellent web site.
1) The first thing I noticed is that it often gives answers that are plain wrong. For…
Part Number: MSPM0L1228-Q1 Tool/software: Dear,
I saw the demo code in SDK, the internal temper sensor config to CH29(INPUT_CHAN_29), and refer volt config to internal reference(VOLTAGE_INTREF)
so my quesiton is
1, is it ok if I select any other channel…
Part Number: TPS25730EVM Tool/software: HELLO,
I try to configure the TPS25760D with the EVM module as follow:
- ADC1 SW position to 1 for 5 V minimum input voltage (34..30mV mesured at the center point the resistor divider network)
- ADC2 SW position…
Hi Edgar Ripoll Vercellone,
Thanks for providing the requested information
It does seem like sensor is adding an error to your system, the plot where you are just measuring a resistor divider looks much cleaner (can you use the same units for all plots…
Part Number: BOOSTXL-DRV8320RS Hello, We are using the BOOSTXL-DRV8320RS and TMS320F28004x with a very small low power motor, roughly 1.8 watts. The motor voltage is 12V and draws roughly 0.15 amps @ 4000 rpm. Max motor current is 0.620 amps.
I see that…
Jake,
The LDOIN voltage is below the minimum required of 5.9. The most likely scenario is the device is not getting enough voltage from the batteries. The voltage required to power the device would be dependent on the exact voltage divider used and bat…
Hi Jesse,
Let me rephrase my question this way:
On the EVM, with the resistive divider and 15 volt feed, the trip voltage for a reset condition is 13.6 volts. If one knew what the PVDD was in a given design, the same 13.6 volts could be generated off PVDD…
Hello Caro,
Thanks for the explanation. This means I will get ±2.7V input-common mode range for ±5V, as I understand.
I am working on the signal chain between a resistor divider network and the ADC. After the resistor divider voltages change…
Hello Foong Wei Seng,
Here you can find the accuracy of the feedback node in PFM as well as in CCM: TPS63070 datasheet | TI.com
The output accuracy is dependent on the feedback node accuracy and the resistor divider accuracy. This tool helps to calculator…
Hi hori,
The modulation circuit is working normally. The Toff becomes longer because Vout drops very close to Vin and volt-second balance is hard to be established. I think the root cause is from the FB divider part. The FB voltage is still around 1.2V…
