XR76116/20
PowerBloxTM 15A and 20A Synchronous Step-Down COT Regulators
Description
The XR76116 and XR76120 are synchronous step-down regulators combining the controller, drivers, bootstrap diode and MOSFETs in a single package for point-of-load supplies. The XR76116 has a load current rating of 15A and the XR76120 has a load current rating of 20A. A wide 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 XR76116/20 provide extremely fast line and load transient response using ceramic output capacitors. They require no loop compensation, simplifying circuit implementation and reducing overall component count. The control loop also provides 0.
