Hi Ambroise,
The DAC output is only grounded when in power down mode. On powerup, the DAC output is 0V (not grounded) which will still cause an un-intended output on the LM51571 until you are able to update the DAC output. For this reason, we recomme…
Part Number: TPL0102-100 Other Parts Discussed in Thread: DAC53701 , DAC53204 Hi,
Is it OK for users to connect two digital potentiometers in series? They wants to use two digital potentiometers as 200kohm on TPL0102-100 for LDO output voltage control…
Hi David,
Unfortunately this is a "bug". The SDO pin of every device in the chain would need to be enabled and saved in NVM before daisy chain can be used. Another user came across this issue a few months ago in the forums as well: https://e2e…
Part Number: DAC53608 Other Parts Discussed in Thread: DAC53204 Hi,
Customer would like to adopt DAC53608 for dynamically adjustable output.
When DCDC doesn't have slew rate control, can user control slew rate of DAC53608 output using output capacitor…
Part Number: TPS543B20 Other Parts Discussed in Thread: DAC53204 We are using DAC53204RTER in our design for voltage margining of +/- 10% for all rails, we are planning to use TPS543B20RVFT regulator for voltage rail 1.1V, as we need to sense the output…
Hi Jones,
Thank you for providing the input for DAC53204 using current mode for voltage margining.
I need one more clarification for this DAC53204. We would like to know about voltage margining in voltage mode.
Can you please guide us with the same spec…
Hi ttd,
I have the DAC53204 block diagram shown below:
Here is the DAC81404 block diagram:
You can see that the FB pin on the DAC53204 is connected to the inverting input of the output buffer, similar to the sense pin of the DAC81404. If you do not…
Hi Ariel,
We do have these two app notes for this application using the DAC53204:
Voltage margining and scaling circuit with current output smart DAC
Voltage Margining and Scaling Circuit with a Voltage Output Smart DAC
The DAC53204 is recommended for…
Part Number: DAC7574 Other Parts Discussed in Thread: DAC53204
Design in the below image is used in our schematic design , Instead of the Data converter part mentioned in the reference design , we have chosen DAC7574 for our design. Is this part suitable…
Hi Ella,
Are you limited to a VID controller? You could look into our DAC53204 which can be used to control a power supply via an I2C, SPI or GPI interface. This cookbook circuit explains how to use the DAC53204 for this purpose. Voltage Margining and…
