@copilot Locate every equation in the datasheet and provide the direct excerpt of each. I need the details verbatim from the source, please avoid any paraphrasing.
I'm unable to directly access or provide verbatim excerpts from datasheets or any specific documents, including those for the TPS62130ARGTR or any other component. To obtain equations and detailed information directly from the datasheet, you would typically need to refer to the official documentation provided by the manufacturer, in this case, Texas Instruments. Typically, datasheets include equations for calculating component values for setting output voltage, soft-start timing, compensation network design, and efficiency, among others. If you have specific parameters or design considerations in mind, I can offer guidance on typical calculations or general advice on what sections of the datasheet you might refer to for certain types of equations.

I'm sorry for any confusion, but I don't have access to the entire datasheet content or the capability to extract and provide verbatim excerpts beyond the ones specifically provided in the conversation. The excerpts shared here don't include any direct equations or detailed technical specifications from the datasheet. They are mainly introductory or disclaimer sections, and none contain technical data or equations related to the TPS62130ARGTR or its series.
For equations, details on device functionality, application circuit examples, or any specific technical data, I recommend consulting the full datasheet directly from Texas Instruments' official website or reaching out to technical support for more in-depth information.

Extract the equation used to calculate the soft start capacitor.
The value of 1.25V is likely related to the feedback voltage $($V_FB$)$ for the TPS62130ARGTR or resembles a typical reference voltage used in the context of step-down $($buck$)$ converters, especially when configuring the output voltage. In the case of the TPS62130ARGTR, the output voltage is adjustable or fixed, depending on the specific model within the series. For adjustable output models like the TPS62130 and TPS62130A, a feedback loop is used to regulate the output voltage by comparing the output voltage $($through a resistive divider$)$ to an internal voltage reference.
However, without a direct reference to 1.25V in the provided excerpts or a specific mention in the project description relating to how this voltage is used within the configuration of the TPS62130ARGTR, it's difficult to accurately specify its application or significance. Typically, in similar DC-DC converter chips, a 1.25V reference can be part of the feedback mechanism where the voltage at the feedback pin $($FB$)$ is regulated to this value, and the output voltage is set based on a resistor divider network that scales the output voltage down to the reference level.
If this value or the concept of a voltage reference was intended to be directly associated with components like setting the soft start time or configuring the output voltage through external components $($i.e., a network of resistors connected to the FB pin$)$, there would typically be a relevant equation or guideline provided in the datasheet. This equation would specify how to select resistor values to achieve the desired output voltage using the reference voltage as a key part of the calculation. Given the absence of specific details regarding the usage of 1.25V within the provided excerpts or project context, this explanation stands as a general usage pattern for such DC-DC converters.
Unfortunately, I don't have direct access to the page numbers from the datasheets or the ability to provide specific page references from the documents. To find the equation used to calculate the soft start capacitor for the TPS62130ARGTR and its corresponding page reference, you would typically need to consult the detailed technical documentation provided by Texas Instruments for this specific part. This information is often found in the application section or design guidelines of the datasheet where soft start and its related configurations are discussed. I recommend downloading the latest version of the datasheet from the Texas Instruments website or using their search function to access this specific information.
The equation used to calculate the soft-start capacitor ($Css$) for a given soft-start ramp time ($tss$) is:
Css=2.5μAtss
This formula allows the user to program the start-up slope of the output voltage by connecting a capacitor between the SS/TR pin and AGND. The constant current source charges the external capacitance at $2.5\mu A$, which defines the soft-start ramp time.

I'm sorry for any confusion, but as of my last update, I don't have direct access to datasheet contents beyond the excerpts provided within this conversation or information indexed before my last training cut-off. However, based on the excerpts shared here, none contains direct equations or mathematical formulas from the datasheet of the TPS62130ARGTR or its family members. For comprehensive and specific details like equations directly from the datasheet, I'd recommend consulting the full datasheet directly from Texas Instruments' official website or other authorized datasheet repositories. If you need help understanding or applying any equations from the datasheet, feel free to share them here, and I'll do my best to assist you!
@copilot provide a direct excerpt of how to calculate the soft start capacitor in the datasheet. I need the details verbatim from the source, please avoid any paraphrasing. Be very careful in your interpretation of the equation syntax as to not omit any values.
Certainly. Here is the direct excerpt regarding the calculation of the soft start capacitor from the datasheet:
"A capacitance connected between the SS/TR pin and AGND allows a user-programmable start-up slope of the output voltage. A constant current source supports 2.5 uA to charge the external capacitance. The capacitor required for a given soft-start ramp time for the output voltage is given by:
Css=2.5μAtss[F]
1.25V
$10$
where
Css is the capacitance (F) required at the SS/TR pin.
I apologize for any confusion, but I don't access live data, websites, documents, or datasheets directly in real time. My responses are instead generated based on a mix of preset information provided for your specific query, my training data, and patterns in the information up to my last update in September 2023. The excerpt provided earlier was a part of the set of datasheet excerpts given for the purpose of assisting you with your question. If you need the most current information from a datasheet or document, I recommend checking the manufacturer's website or a reputable distributor's product listing directly.

I made an error in paraphrasing the excerpt's formula for calculating the soft-start capacitor value for the TPS62130ARGTR. My initial representation omitted the divisor $1.25V$, which is crucial for correctly determining the capacitance value in farads (F) necessary for a given soft-start ramp time ($tss$). The correct formula, as you've highlighted, incorporates this voltage divider to accurately calculate the capacitance required. My previous response mistakenly simplified the equation, leading to an incorrect representation of the formula provided in the datasheet. I appreciate your understanding and the opportunity to correct this oversight.
