The datasheet for the MPM3551 says “Additional output voltages
may be available. Contact MPS for details.” but the output voltage is adjustable in the default part number (MPM3551GQWE-AEC1-Z)?
Is there any reason why I cannot set the output voltage to 6V by changing the feedback resistors? The datasheet does not mention how to select the feedback resistors to set the output voltage and only has the two application circuits for 3.3V and 5V.
Thanks
Hi @joshr,
Thank you for posting on the MPS Technical Forum.
Recommended operation of the MPM3551 is Vout,max = 0.95 * Vin .
With the adjustable output configuration (implementing an external resistor divider to the FB pin), you can calculate the resistor divider values. Please refer to Equation 11 in the datasheet on Page 28.
You may use R5 = 100kOhm as shown in other datasheet typical application circuits.
Thank you, Will
