XRP7740ILB-0X18-F

Overview

The XRP7740ILB-0X18-F is a specialized Power Management IC (PMIC) from MaxLinear's PowerXR series. It integrates five output channels, comprising four synchronous buck converters and one linear regulator (LDO). The device operates with an input voltage range of 6.5V to 20V and supports switching frequencies up to 1.5MHz. Designed for surface mount assembly, it is housed in a 40-TQFN package measuring 6x6 mm with an exposed pad. The component supports programmable sequencing and functions within an operating temperature range of -40°C to 125°C.

Feature Summary

• Integrates four synchronous buck regulators and one LDO in a single compact package
• Supports digital power control via I2C interface for programmable outputs
• Features built-in sequencer for controlled power-up and power-down timing

Applications

• Portable electronic devices requiring multi-rail power distribution
• Industrial equipment utilizing digital power management systems
• Communication infrastructure components needing synchronized voltage rails

Procurement Notes

This component is designated as obsolete by the manufacturer. Verification of availability should focus on remaining stock from authorized distributors or secondary market sources. Confirm that the specific suffix matches the required electrical characteristics, as ordering suffixes may indicate variations in packaging or testing standards. Ensure compliance with end-of-life transition plans for ongoing production needs.

Selection Notes

Select this PMIC when a design requires multiple regulated outputs from a single high-voltage rail with digital control capabilities. The integrated sequencer simplifies board layout by managing startup order automatically. Consider the thermal performance of the exposed pad TQFN package for heat dissipation requirements. Verify that the I2C interface compatibility aligns with the system controller specifications.
