Programmable Power Management Systems


The XRP7714 is a quad-output Pulse-Width Modulated (PWM) step-down DC/DC controller with a built-in LDO for standby power and GPIOs. The device provides a complete power management solution in one IC and is fully programmable via an I2C serial interface. Independent Digital Pulse Width Modulator (DPWM) channels regulate output voltages and provide all required protection functions such as current limiting and overvoltage protection.

Each output voltage can be programmed from 0.9V to 5.1V without the need of an external voltage divider. The wide range of the programmable DPWM switching frequency (from 300kHz to 1.5MHz) enables the user to optimize between efficiency and component size. Input voltage range is from 4.75V to 25V. An I2C bus interface is provided to program the IC as well as to communicate with the host for fault reporting and handling, power rail parameters monitoring, etc.

The device offers a complete solution including independently programmable: soft-start, soft-stop, start-up delay and ramp of each PWM regulator.

The Exar Configuration Model XR77xxEVB-XCM-V80 interface board provides designers with a simple, quick and inexpensive means of evaluating and prototyping new designs using Programmable Universal PMIC devices with PowerArchitect4. This Evaluation Board is designed only for low volume engineering purposes; not production volumes. For production requirements commercial programmers must be used. The Evaluation Board is provided “as is and whereas” and without any warranty as to results, merchantability or purpose. Exar is not responsible for misuse of the Evaluation Board.
