Description

The RT6278B is an advanced constant on-time (ACOT™) mode synchronous buck converter. The main control loopof the RT6278B using an advanced constant on-time (ACOT™) mode control which provides a very fast transientresponse. The RT6278B operates from 4.5V to 23V input voltage, the output voltage can be programmed between0.6V to 5.1V.EVB_ RT6278BHGQUF-00
