9.4 Resistor and Vout Values (Calculated)

The components listed in the Resistor and Vout Values section, Figure 10, are calculated by the inputs in

the Initial Setup section. The Resistor and Vout Values section will provide the user with the standard

components needed to make a working design. The component designators are reflected in the schematic

to the right of this section.

The first component in the Resistor and Vout Values section is the RSET resistor. This resistor is chosen

based on the input in the IDAC at Startup box. This resistor will match the resistors listed in the electrical

characteristics table in the LM10011 datasheet.

The feedback resistors RFB1 and RFB2 are calculated based on the VOUT MIN and VOUT MAX range

set in the Initial Setup section. The values in the RFB1 and RFB2 spin boxes represent calculated

theoretical values and can be changed manually at the users discretion if needed. The RFB1 and RFB2

(Nearest 1%) values represent standard E96 1% resistor values available on the market.

Using the nearest 1% RFB1 and RFB2 resistor values, the actual VOUT MIN and VOUT MAX along with

the VOUT resolution and initial startup voltage is calculated. This gives the user a more realistic preview of

what they can expect to see at the output of the POL under VID control using standard size resistors.
