TPS63051: Added the FB resistor to change output voltage

Part Number: TPS63051
Other Parts Discussed in Thread: TPS63050

Hi, Team

My customer used TPS63051 to convert voltage to system.

If they want to change output voltage by external resistor on FB pin.

Could we add the external resistor to change output voltage on TPS63051?

    Hi Ray,

    In theory it would be possible, but it would be pretty hard to calculate the exact resistor values needed to set the desired output voltage. the reason is, the internal feedback divider of the TPS63051 do not have accurate intrinsic values .

    The TPS63050 has the same footprint the voltage can easily be changed a feedback divider network with a switch. Can the customer consider doing that? What is the end application?
