Okay, this is a datasheet excerpt for a switching regulator or similar power supply module. It appears to be listing different output voltages, corresponding resistor values for adjustment, and perhaps related specifications. Here's a breakdown of what I see and a summarization:

Overall Structure

The document is organized in a table-like format with several columns. It looks like it's presenting configurations for adjustable output voltages.

Key Columns/Sections

1. Vout (nominal): This column lists the standard, fixed output voltage options available for the module (1.2V, 1.8V, 2.5V, 3.3V, 5.0V).

2. Vout (adj): This is likely where the adjustable output configurations are shown. The values listed (0.8V, 0.9V, 1.0V, etc.) are the target adjustable output voltages.

3. Resistor Values (R1, R2): These columns show the resistor values (in Ohms) that need to be used in a voltage divider network to set the output voltage. The module likely uses feedback to maintain the desired output voltage, and the resistor values determine the feedback voltage. Where there are blanks, it suggests the values may not be needed or provided for that specific output.

4. Other sections: The last sections show a table of resistor values for different output voltages.

Summary of Information

️· Adjustable Output: The module allows for a range of adjustable output voltages.
️· Voltage Divider: The output voltage is adjusted using a voltage divider network consisting of two resistors (R1 and R2). The datasheet provides a table of R1 and R2 values for various desired output voltages.

️· Fixed Options: The module also supports several fixed output voltages (1.2V, 1.8V, 2.5V, 3.3V, and 5.0V).
️· RECOM Power: The datasheet is from RECOM Power, a manufacturer of power supplies.

How to Interpret the Resistor Table

To set a specific adjustable output voltage:

1. Find the desired output voltage in the "Vout (adj)" column.
2. Read the corresponding R1 and R2 values from the resistor value columns.
3. Connect the resistors in a voltage divider configuration as per the module's documentation (likely between the output and ground, and the feedback pin).
4. Verify the output voltage with a multimeter after powering up the module.

Important Notes:

️· Module Documentation: This is just an excerpt. You *must* refer to the full datasheet or module documentation for complete instructions, schematic diagrams, and safety precautions.
️· Resistor Tolerance: Resistor tolerance will affect the actual output voltage.
️· Feedback Connection: The datasheet assumes the voltage divider is connected to the appropriate feedback pin on the module.
️· Input Voltage: Make sure the input voltage is within the specified range of the module.
️· Load Current: The output current capacity of the module is also important.
