April 4, 2016– Exar Corporation a supplier of analog mixed-signal products serving the industrial, high-end consumer and infrastructuremarkets, announces the XR79103, XR79106, XR79203 and XR79206 additions to its family of synchronous, step-down power modules with input voltage up to 40V. All four single output devices rise in a compact QFN package that includes integrated power converters including MOSFETs, inductors and a high frequency input capacitor.
The XR79103 and XR79106 operate from a 4.5V to 22V input supply, delivering a regulated output adjustable between 0.6V to 5.5V. With 40V maximum input voltage, the XR79203 and XR79206 add the ability to convert from loosely regulated 24VDC, rectified 18VAC and 24VAC sources.
The output voltage can be set from 0.6V to 13.2V. These modules offer supervisory and protection features for proper sequencing, safe operation under abnormal operating conditions and light load operation. The combination of wide input voltage range, a thermally efficient package, tight regulation accuracy and small solution size makes these power modules well suited for applications in communications, drones and remote vehicles, industrial, after market automotive and FPGA and SOC power systems.
