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 […]

DC-DC converter handbook covers GaN transistors
The demand for information is growing at unprecedented rates and society’s insatiable appetite for communication, computing and downloading, is driving this demand. With emerging technologies, such as, cloud computing and the internet of things, not to mention the 300 hours of video being loaded to YouTube every minute, this trend for more and faster access […]
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 […]
