MaxLinear XR76108 & XR76112 PowerBlox™ COT Regulators
MaxLinear XR76108 and XR76112 PowerBlox™ 8A and 12A Synchronous Step Down COT Regulators are a combination of a controller, drivers, bootstrap diode, and MOSFETs in a single package for point-of-load supplies. The XR76108 and XR76112 offer load current ratings of 8A and 12A. A wide 4.5V to 22V input voltage range allows for single supply operation from industry standard 5V, 12V, and 19.6V rails. With a proprietary emulated current mode Constant On-Time (COT) control scheme, the XR76108 and XR76112 provide extremely fast line and load transient response using ceramic output capacitors.
The MaxLinear XR76108 and XR76112 PowerBlox COT Regulators are offered in a space-saving 5.0mm x 5.0mm QFN30 package.
