Description

This low ripple power supply reference design supports a 1.2V output voltage at up to 3A of current from a 3.8V to 30V input. Such a low ripple voltage is required for many applications such as ADC, RF transceiver, and analog front end (AFE). Using the TPS62933F power converter combined with a second stage LC filter enables a very simple low ripple power design to create a 1.2V output voltage at 3A currents.
