A recent trend in the design of portable devices has beento use ceramic capacitors to filter DC/DC converter inputs.Ceramic capacitors are often chosen because of theirsmall size, low equivalent series resistance (ESR) and highRMS current capability. Also, recently, designers havebeen loo ...
Removing output capacitors saves money and boardspace. Linear Technology’s OPTI-LOOPTM architectureallows you to use the output capacitors of your choice andcompensate the control loop for optimum transientresponse and loop stability. Figure 1 shows the dramaticimprovement possible ...
