Part Number: TAS5717
I make the TAS5717 circuit as attached.
Could you review it and let me get the result?

Hi Nicky, Overall looks good. For your 6-bit voltage translator I noticed the following in the datasheet 1) "To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor" -- this might be something to consider. 2) "If pull up or pull down resistors are needed, the resistor value must be over 50 kΩ." -- you have a 10K pull-up on PDN In the boost circuit: 3) The application schematic has 22uF capacitors from Vout to GND next to the device before the feedback resistors. I couldn't tell if you had a reason for leaving those caps out. 4) ILIM peak current limit is set at 3.4A whereas over current on the TAS5717 is 4.5A. This may limit your output power. I'd double check that your boost converter will output the desired power without exceeding the 3.4A current limit. Regards, Alex
