Description

It is a non synchronous buck controller. It uses a constant on time (COT) device i.e. LM5085. This circuit has ceramic output capacitors which have very low ESR. Therefore the ripple is generated using the DCR of the inductor. The ripple voltage is then superimposed onto the feedback voltage.
