Exar ’s Power XR Digital Power Solutions
Exar’s Power XR ICs integrate the best of both worlds; the low cost and flexibility of digital power control as well as the robust
power capabilities of high performance analog power switches. Power XR products reduce development time from weeks to
hours, enabling a significant time-to-market advantage for system design engineers.
Additionally, Exar’s Digital Power Studio? is an easy to use software environment, empowering engineers to create complex
sequencing schemes and power systems, and modify voltage, current or other parameters in seconds.

The Power XR Product Family
The Power XR family is comprised of five Pluse-Width Modulated (PWM) step-down DC-DC controllers with a built-in LDO for standby
power and GPIOs. The XRP7704, XRP7708, XRP7713, XRP7714, and XRP7740 devices provide a complete power management
solution in one IC and are fully programmable via the included I2C serial interface. Independent Digital Pulse-Width Modulator
(DPWM) channels regulate output voltages and provide all required protection functions such as current limiting and over-
voltage protection.
