How mixed-type output capacitors affect DC/DC converter stability

October 6, 2015 By Aimee Kalnoskas 1 Comment

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?

September 3, 2015 By Aimee Kalnoskas Leave a Comment

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 […]

Metalized Polypropylene Film Capacitors for Power Applications

February 28, 2012 By admin Leave a Comment

The MPP Series film capacitors from Illinois Capacitor are available in a range of capacitance values from 4.7 to 35μF with voltage ratings of 500 to 1,500WVDC. Packaged in a flame-retardant hard-plastic case, each is well suited for high-reliability power conversion and control applications. Tab-style terminals are tinned copper with positioning points for on-board stability and performance. […]
