AEC-Q100-qualified PoL regulators simplify system design
AEC-Q100-qualified 40V switching regulators have been released by Exar, for automotive applications such as infotainment head units and advanced driver assistance systems (ADAS).
The XR76203-Q, XR76205-Q and XR76208-Q are 3A, 5A and 8A synchronous step-down regulators designed to provide 5.5 to 40V input and adjustable output down to 0.6V. The company says that the XR76208-Q is the highest current (8A), fully synchronous, 40V regulator, offering AEC-Q100 qualification, available today.
The XR7620X-Q family features proprietary emulated current mode constant on-time (COT) control loop. It provides fast transient response with ceramic output capacitors, with supervisory and protection features for proper sequencing, safe operation under abnormal operating conditions and light load operation.
This regulator family meets the AEC-Q100 qualification requirements for Temperature Grade 1 (-40 to 125 degree C), HBM ESD Class Level 2 and CDM ESD Class Level C4B. They are offered in a 5.0 x 5.0mm QFN which is RoHS-compliant, and halogen-free, with wettable flanks, allowing for 100 per cent automatic optical inspection of solder wetting post-assembly.
