Its dual-cap design uses four ceramic capacitors to provide ultra-low output ripple with high efficiency, while eliminating the need for inefficient linear regulators. The TPS6024x devices operate down to 1.8 V, supporting a 3.3-V, 2.7-V, 3-V output from two-cell, nickel- or alkaline-based chemistries,...
