When designing a high-precision data application, one priority is to control the switching noise of the DC/DC converter, especially in power-save modes with transient bursts that generate a high output voltage ripple. One way to reduce ripple is to minimize the energy package sent to the output in a switching cycle. But what if that’s not enough?
The TPS62840 buck converter, which has an IQ of 60nA, has a STOP pin that immediately stops the regulator switching after the current switching cycle, opening a window of complete switching silence (see Figure 12).
