AEC-Q100 qualified, 40V PoL regulators
Exar's AEC-Q100 qualified family of 40V switching regulators is intended for automotive applications such as infotainment head units and Advanced Driver Assistance Systems (ADAS).
By Graham Prophet , Feb. 13, 2017 –
The XR76203-Q, XR76205-Q and XR76208-Q are 3A/5A/8A synchronous step-down regulators designed to provide a 5.5V to 40V input voltage range and an adjustable output voltage down to 0.6V while providing excellent transient response and output accuracy over the entire voltage range.
The XR76208-Q is believed to be the highest current (8A), fully synchronous, 40V regulator on the market that offers AEC-Q100 qualification. The XR76203/5/8-Q family features Exar's emulated current mode Constant On-Time (COT) control loop. It provides fast transient response with ceramic output capacitors and excellent line and load regulation while simplifying system design. The family also offers supervisory and protection features for proper sequencing, safe operation under abnormal operating conditions and light load operation.
