The XR76203-Q, XR76205-Q and XR76208-Q are 3A/5A/8A synchronous step-down regulators designed to provide a wide 5.5V to 40V input voltage range and an adjustable output voltage down to 0.6V.

The XR76208-Q is the highest current (8A), fully synchronous, 40V regulator on the market that offers AEC-Q100 qualification, says the company.

The XR76203/5/8-Q family features proprietary emulated current mode constant on-time (COT) control loop. It provides fast transient response with ceramic output capacitors, with line and load regulation, while simplifying system design. There are supervisory and protection features for proper sequencing, safe operation under abnormal operating conditions and light load operation.

The regulator family meets AEC-Q100 qualification requirements for Temperature Grade 1 (-40 to 125°C), HBM ESD Class Level 2 and CDM ESD Class Level C4B.   

The family is available now in RoHS-compliant, green/halogen free, space-saving 5.0 x 5.0mm, 30pin QFN packages with wettable flanks.
