Exar XRP6124 Non-Sync Step Down Controllers
The Exar XRP6124 is a 5A Point-of-Load capable non synchronous step down (buck) controller. This Exar step down controller features a wide 3V to 30V input voltage range that allows for single supply operation from industry standard 3.3V, 5V, 12V, and 24V power rails. The XRP6124 has a proprietary Constant On-Time control scheme that allows it to provide extremely fast line and load transient response while the operating frequency remains nearly constant. Exar XRP6124 step down controllers target a variety of applications, including point-of-load conversion, audio-visual equipment, and distributed power architecture.
