PRODUCTION DATA
The TPSM336x5 output voltage can be set by two external resistors, RFBT and RFBB. Connect RFBT between VOUT at the regulation point and the FB pin. Connect RFBB between the FB pin and AGND.
The TPSM336x5 has an adjustable output voltage range from 1.0 V to 15 V. To ensure that the power module regulates to the desired output voltage, the typical minimum value for the parallel combination of RFBT and RFBB is 5 kΩ while the typical maximum value is 10 kΩ as shown in Equation 3. Equation 2 and Equation 3 can be used as a starting point to determine the value of RFBT. Reference Table 7-1 for a list of acceptable resistor values for various output voltages.
For adjustable output options, an addition feedforward capacitor, CFF, in parallel with the RFBT can be needed to optimize the transient response. See CFF Selection for additional information.
