James explores whether multi-layer ceramic #capacitors (MLCCs) can be replaced with polymer electrolytic capacitors, specifically KO-Caps, in a DC-to-DC converter. He compares the performance of both capacitor types, discussing the MLCC's DC Bias Effect, which reduces capacitance under load, and how KO-Caps avoid this issue. Through a series of tests on an evaluation board, James measures ripple and capacitance in various configurations and highlights the trade-offs between MLCCs and polymers in terms of performance, cost, and board space. Ultimately, the video offers insights into when it might make sense to switch from ceramics to polymers in power conversion designs! bit.ly/4ijxepg
