XRP7713ILBTR-F

Overview

The XRP7713ILBTR-F is a PowerXR series PMIC featuring three synchronous buck regulators and one LDO. It operates within an input voltage range of 4.75 V to 25 V, with output voltages adjustable from 0.9 V to 5.1 V for the buck channels. The device supports switching frequencies between 300 kHz and 1.5 MHz. It includes integrated sequencing logic and functions in temperatures from -40°C to +125°C. Packaged in a 32-TQFN (5x5 mm) case, it draws 28 mA operating current.

Feature Summary

• Integrates three high-efficiency synchronous buck converters and one low-dropout linear regulator for multi-rail power distribution.
• Features digital control capabilities allowing programmable parameters through PC interface or I2C communication protocols.
• Includes built-in sequencing logic to manage power-up and power-down transitions across multiple output rails.

Applications

• Powering complex system-on-chip architectures requiring multiple independent voltage levels.
• Embedded computing platforms needing synchronized power rail management.
• Industrial equipment operating in extended temperature environments.

Procurement Notes

Verify component authenticity through authorized MaxLinear distributors due to end-of-life status. Confirm package marking and date codes against official datasheets. Check for moisture sensitivity level compliance during storage and handling. Ensure ordering suffixes match specific revision requirements.

Selection Notes

Select this part when designing systems requiring four regulated outputs from a single wide-input voltage source. Consider the 32-TQFN footprint constraints and thermal dissipation requirements for the exposed pad. Evaluate if the integrated sequencing meets system startup timing needs without external logic.

Part Context

Part of the MaxLinear PowerXR family designed for digital power management applications. It succeeds earlier analog controllers by offering software-configurable parameters. The series targets high-density power solutions where board space and efficiency are critical design drivers.
