Renesas — How to Protect Buck Regulators from Over-Current Damage

FTMSept2018-DN-Renesas-tile-200x200

A synchronous buck regulator will often be used in an industrial application to step down 12V rails to point-of-load inputs, sometimes supplying a voltage as low as 0.6V to a microcontroller, FPGA, memory IC or peripheral I/O. In these cases, Over-Current Protection (OCP) is necessary to protect the switching regulators from damage caused by excessive […]
