5A capable 3-ch power IC for FPGA and SoCs

The power management IC XR77103 from Exar allows design engineers to parallel three of its outputs each with 2 A rating, so that they can get a higher current rate of 5A, that's possible because each of this power regulation circuit/channel employ current more control architecture. This device measuring 4 x 4 mm in dimensions is suggested for processor chips such as FPGAs, SoCs, DSPs and video processors.

The output voltage (from 0.8V to 6V) as well as switching frequency (from 300kHz to 2.2MHz) can be controlled through an i2c interface.

XR77103 is supported by a new release of PowerArchitect design and configuration software.

The XR77103 can be supplied with input voltage with the variation in the range of 4.5V to 14V. A mode called Pulse Skipping can be enabled to increase the efficiency at light loads.

Packaged in a 4x4mm QFN, XR77103ELB-A0R5 and –A1R0 are fixed at switching frequencies of 500kHz and 1MHz, respectively. Both products feature a 0.8V, high accuracy reference (1%) and their output voltages are set by external resistors.

“The XR77103 Universal PMIC with integrated MOSFETs showcases Exar’s enhanced integration capability for monolithic power solutions," said Tuomas Hollman, Exar’s vice president, power management products. “This extends our portfolio to cover systems that require multiple low current rails in a highly integrated solution, making the XR77103 an ideal fit for applications such as projectors, displays, industrial HVAC systems and home gateways.”

Availability and price: The XR77103ELB, XR77103ELB-A0R5 and XR77103ELB-A1R0 are available in RoHS compliant, green/halogen free, space-saving 4x4 QFN packages. Prices start at $1.95, $1.60 and $1.60, respectively, in quantities of 1,000.
