Part Number: TPS63710
Other Parts Discussed in Thread: TPS62147

I want to use TPS63710 for 'Vin : 12V, Vout : 2.5V' (not negative Vout)

The reason that I use this model though it is inverting Buck converter is this model has very low output ripple.

I don't want to use LDO post Switching Regulator.

How can I change 'inverting Buck converter' to'non inverting Buck converter'?

Hi User,

It is not possible to use this device to create a positive voltage.

The TPS62147/8 has a forced PWM mode, which also creates lower ripple by disabling the power save mode. How much ripple can you accept?
