Exar Corporation Releases Triple-Channel Universal PMIC

The XR77103 features an I2C interface allowing customers to control output voltage (from 0.8V to 6V), switching frequency (from 300kHz to 2.2MHz), power sequencing, and current limit. The XR77103 is supported by a new release of PowerArchitectTM 4 design and configuration software.

It operates from a 4.5V to 14V input supply and all three outputs are designed for 2A load currents with peak currents up to 3A. A selectable Pulse Skipping Mode (PSM) results in improved efficiency at light loads, a key feature in meeting standby energy requirements or extending battery life, Exar states.

“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.”
