XR79206

XR79206 40V, 6A Synchronous Step-Down COT Power Module Description The XR79206 is part of a family of 40V synchronous step-down power modules combining the controller, drivers, inductor, passive components and MOSFETs in a single package for point-of-load supplies. This module requires very few external components leading to ease of design and fast time to market. The XR79206 has load current rating of 6A. A wide 5V to 40V input voltage range allows for single supply operation from industry standard 24V ±10%, 18V to 36V and rectified 18VAC and 24VAC rails. With a proprietary emulated current mode Constant On-Time (COT) control scheme, the XR79206 provides extremely fast line and load transient response using ceramic output capacitors. It requires no loop compensation, simplifying circuit implementation and reducing overall component count. The control loop also provides 0.2% load and 0.1% line regulation and maintains constant operating frequency. A selectable power saving mode, allo...
