How To Solve Frequency Jitter In Constant On-Time POLs With A Ripple Injection Circuit


The purpose of this article is to walk through the steps of implementing a ripple injection circuit for constant on-time POLs. It covers how to connect the circuit and then how to calculate the values used in the circuit. Frequency jitter can be caused by a number of things such as noise injection into the voltage sense lines from outside sources, to very low ripple current in the output ind... » read more
