Hi,
How many Watts is the 10k resistor rated for.
Is it possible to swap the Zenner-diode circuit with an LDO?
Do D1 and Q1 comply with this e2e (+) BQ34110: Relates to bq34110 EVM Schematic - Power management forum - Power management - TI E2E support…
Hi Yehoram,
1. 1A LDO is much higher current rating than necessary. Supply current for the Vdd pin is dependent on switching frequency, Figure 1 in the data sheet has a graph that shows the VDD current across frequencies.
2. We don't have parts that come…
Hi Manoj,
Manoj Turpati said: Thanks for the response. I would like to calculate Maximum output voltage of the transformer after rectification. I assume VO-max in the equation(10) refers to maximum output voltage of the LDO(based on the example & Eq -11…
Hi,
Could you share the schematic in a searchable PDF instead of an image? The schematic can also be shared by private E2E message if that is preferred. In the meantime, here is my feedback:
VSEL_SD cannot be left floating. LDO1 is configured as bypass…
Hi Dave,
We recommend to keep the ADC and DAC powers separated.
For the DAC, if the customer truly wants to utilize the phase noise performance of this device, then they should replicate the DAC EVM power supply circuits 5X times.
For the ADC, you can…
Hi YC Hsu,
Typically we use the TPS7A4700 on our EVMs, which is a low noise LDO with adjustable output.
If you need a fixed output, consider the TPS7A20 devices
You can also review all of our LDOs at this link: https://www.ti.com/power-management/linear…
Okay thanks, we'll take a look to see if the LDO can meet this target noise across this frequency spectrum. We'll likely test with the adjustable version as well because we can add a Cff (feedforward capacitor) across the top setpoint resistor which…
Hi Tim,
I understand your concern on TPS76701QD being an older IC and expensive. Yes, you can choose any LDO that you believe works best for your requirements, this shouldn't have any impact on ISOUSB111 performance.
TLV76701DGNR seems to be in a…
Part Number: TMS320F280049C-Q1 Hello ,
Could you please provide feedback for the below queries:
1. I f the orderable part number or MPN F280049CPZQR is a automotive qualified part.
If not please let know the orderable part number.
2. Is monitoring VDDIO…
Hello Ravi,
Referring to the TRM, when the gauge is in shutdown mode, the LDO output will be disabled. Please see the image below taken from the TRM.
Additionally, if the gauge is in shutdown mode, you will not be able to communicate with the gauge.…
