Part Number: TPS53679
Other Parts Discussed in Thread: CSD95480RWJ

Good afternoon!

Interested in the launch/launch of the TPS53679 and CSD95480RWJ x5pc.

What is the output voltage of the CSD95480RWJ when I first turn it on?

Interested in two states:

1. TPS53679 controller stitched/stitched with basic firmware.

2. The TPS53679 controller is caught in a board without firmware.

Добрый день!

Интересует старт/запуск связки контроллера TPS53679 и CSD95480RWJ х5шт.

Какое выходное напряжение на выходе CSD95480RWJ при первом включении?

Интересует 2 состояния:

1. контроллер TPS53679 прошит/зашит базовой прошивкой.

2. контроллер TPS53679 запаян в плату без прошивки.

Hello, all TPS53679 devices ship programmed with the default values mentioned in the datasheet. The default Vboot for this device is 1.7V for channel A and 0.9V for channel B. You can reprogram the Vboot value through the PMBus interface and store it to NVM later if needed.

Thank you! understandable, but there is no such data (about which you are talking) in the description of the chip.

Спасибо! понятно, но этих данных нет (про которые вы говорите) в описании микросхемы.

The document on ti.com is just the front page/description. You can email vr [at] list [dot] ti [dot] com to get the full datasheet, but they will need to check the NDA status with TI to send it. If you already have the full document, you can see it as the default value for VOUT_COMMAND in the PMBus command table on pg 48.

Thank you, a VR request has already been sent. It is not clear what actions are being done or not.

Matt, tell the go - controllers are sold stitched with basic firmware? Here for example - ru.mouser.com/.../TPS53679RSBT

Спасибо, запрос на VR уже был послан. Какие то действия выполняются или нет - не ясно.

Matt, подскажи - контроллеры продаются прошитые базовой прошивкой? здесь например - ru.mouser.com/.../TPS53679RSBT

Yes the controllers are sold pre-loaded with NVM defaults as per the full datasheet. They should be checking your NDA status . I suggest to ping them again if you’ve not heard back in a day or two.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
