How mixed-type output capacitors affect DC/DC converter stability
by Akshay Mehta and Yang Zhang, systems and applications engineers, Texas Instruments DC/DC converters are often used in distributed power-supply architectures for industrial applications. Many architectures use two types of output capacitors: One has higher capacitance and higher equivalent series resistance (ESR), such as aluminum electrolytic, while the other has much lower ESR and relatively […]
Ceramic or electrolytic output capacitors in DC/DC converters – Why not both?
By Michael Score, Texas Instruments Switching power supplies are used in almost every end-equipment that needs a long battery life, low heat generation, or to meet ENERGY STAR® guidelines. When designing a switching power supply, it is difficult to decide which output capacitor type to use. Electrolytic capacitors have high equivalent series resistance (ESR), making […]
