Fully-integrated step-down regulators for compact point-of-load supplies

Exar's XR761xx PowerBlox CoT regulators are now available from Mouser stock. The synchronous step-down regulators combine the controller, drivers, bootstrap diode and MOSFETs in a single package for point-of-load supplies. The devices have a current load rating of 8A (XR76108), 12A (XR76112) or 15A (XR76115). A wide 4.5V to 22V input voltage range allows for single supply operation from industry standard 5V, 12V and 19.6V rails for applications such as distributed power architecture, point-of-load (PoL) converters, power supply modules, FPGA DSP / processor supplies, base stations, switches / routers and servers.
