Press Release Summary:
Housed in 10 x 10 x 4 mm and 12 x 12 x 4 mm QFN packages, respectively, 10 A Model XR79110 and 15 A Model XR79115 use patented emulated current mode constant on-time control, which enables operation with ceramic output capacitors, eliminating loop compensation components. Both single output, synchronous step-down power modules convert from common input voltages such as 5, 12, and 19 V. Output voltage can be set from 0.6–18 V with full range 0.1% line regulation and 1% output accuracy.

Exar Introduces Industry's Smallest High Current Power Modules
10A and 15A Modules Provide Market Leading High Power Density
Fremont, Calif, – Exar Corporation (NYSE: EXAR), a leading supplier of high-performance integrated circuits and system solutions, today introduced the 10 amp XR79110 and 15 amp XR79115 single output, synchronous step-down power modules using Exar’s patented emulated current mode constant on-time (COT) control. Both devices provide easy to use, fully integrated power converters including MOSFETs, inductors, and internal input and output capacitors in a compact 10x10x4mm and 12x12x4mm footprints respectively. The XR79110 and XR79115 offer versatility to convert from common input voltages such as 5V, 12V and 19V.
The XR79110 and XR79115 use Exar’s emulated current mode COT control scheme that has the fast transient response of conventional COT control loops while providing excellent line and load regulation performance. Exar's COT control loop enables operation with ceramic output capacitors, eliminating loop compensation components, a key to high module integration. The output voltage can be set from 0.6V to 18V and with exceptional full range 0.1% line regulation and 1% output accuracy over full temperature range. These modules offer a host of supervisory and protection features for proper sequencing, safe operation under abnormal operating conditions and light load operation.
“These devices extend Exar’s existing power module family to high-current single channel solutions for various end applications,” said James Lougheed, Exar’s vice president, power management products. “These modules use a QFN based package technology to provide superior thermal performance and manufacturability all in the smallest footprint on the market. Additionally, access to the QFN package pins facilitates accurate measurements and board debugging.”
Exar will be discussing this new family of devices at booth A6.169 at Electronica 2014 in Munich, Germany, November 11-14th. To request a meeting, please email press@exar.com.Â
Product Availability and Pricing
The XR79110 and XR79115 will be available on November 11th in RoHS compliant, green/halogen free, space-saving 10x10x4mm and 12x12x4mm QFN packages. The XR79110 and XR79115 are priced at $8.95 and $10.95 respectively in 1,000 piece quantities.
