RT2872 Overview
The RT2872 is a high efficiency, current-mode synchronous step-down DC/DC converter that can deliver up to 3A output current over a wide input voltage range from 4.5V to 36V. The device integrates 105mΩ high-side and 80mΩ low-side MOSFETs to achieve high conversion efficiency. The current-mode control architecture supports fast transient response and simple external pensation.
