Exar Corporation (Fremont, CA) introduced a new line of high-power switching regulators to add to its popular PowerBlox family of DC-DC converter products. The XR76108, XR76112 and XR76115 are Synchronous Step Down Regulators supporting point-of-load (POL) supplies of 8A, 12A, and 15A, respectively. The XR761xx family is designed to achieve excellent transient response and output accuracy using Exar's proprietary emulated current mode Constant On-Time (COT) control loop. These devices deliver core voltage rails for ASICs, FPGAs, DSPs and Network Processors in communications, networking, and industrial markets. Other features include:

• Input voltage range of 4.5V to 22V.
• Adjustable output voltage from 0.6V to 18V.
• 0.1% line regulation across the entire input voltage range and 1% output accuracy over full temperature range.
