Exar – New 22V/40V input power modules (XR79103, XR79106, XR79203 and XR79206) deliver 3A/6A full current at over 95% efficiency

Exar has launched the XR79103, XR79106, XR79203 and XR79206 synchronous step-down power modules operating from input voltages up to 40V. All four single-output devices, which are housed in compact QFN packages, feature high operating efficiency and low temperature rise.

The XR79103 and XR79106 provide a regulated output adjustable between 0.6V and 5.5V. The output-voltage range of the XR79203 and XR79206 is 0.6V to 13.2V.
