Non-Synchronous PFET Step-Down Controller
Rev. 1.1.0
GENERAL DESCRIPTION
The XRP6124 is a non synchronous step down (buck) controller for up to 5Amps point of loads. A wide 3V to 30V input voltage range allows for single supply operations from industry standard 3.3V, 5V, 12V and 24V power rails.
With a proprietary Constant On-Time (COT) control scheme, the XRP6124 provides extremely fast line and load transient response while the operating frequency remains nearly constant. It requires no loop pensation hence simplifying circuit implementation and reducing overall ponent count. The XRP76124 also implements an emulated ESR circuitry allowing usage of ceramic...
