The TPS62913 17-V, 3-A DC/DC buck converter reaches levels of output noise and ripple never before possible with a switching regulator. With 20-μVrms noise and less than 10-μVrms ripple, the TPS62913 powers sensitive analog loads like the AFE7950 RF sampling transceiver without the need for a post-regulator LDO- saving cost, reducing power supply size, and enhancing efficiency.
