XRP7724ILB-F

Overview

The XRP7724ILB-F is a PowerXR PMIC featuring six outputs: four synchronous buck converters and two low-dropout regulators. It operates within a 4.75V to 25V supply range and supports switching frequencies from 105kHz to 1.23MHz. The device integrates sequencing control for power management. It is housed in a 44-TQFN (7x7mm) package with an exposed pad, designed for surface-mount installation across a -40°C to +125°C operating temperature range.

Feature Summary

• Integrates four synchronous buck converters and two linear regulators for multi-rail power distribution
• Includes internal sequencing logic to manage power-up and power-down transitions
• Supports programmable switching frequencies ranging from 105kHz to 1.23MHz

Applications

• Multi-output power systems requiring synchronized buck and LDO regulation
• Industrial or commercial equipment needing wide input voltage support
• Embedded systems utilizing digital power management architectures

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and pin alignment against the 44-TQFN specification.
