XRP7704ILB-F

Overview

The XRP7704ILB-F is a quad-output digital PWM buck controller with an integrated LDO, manufactured by MaxLinear. It operates within a 6.5V to 20V input voltage range and provides four independent step-down channels with output voltages programmable from 0.9V to 5.1V. The device features fully programmable DPWM frequencies between 300 kHz and 1.5 MHz, configurable GPIOs, and comprehensive protection including OTP, UVLO, OCP, and OVP. It is housed in a 40-TQFN (6x6) package.

Feature Summary

• Fully programmable via I2C interface for system configuration
• Independent digital pulse width modulation channels with PID control
• Integrated non-volatile memory for persistent system settings

Applications

• Multi-rail server power distribution networks
• Telecommunications base station power systems
• Industrial equipment requiring precise multi-voltage regulation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and temperature grade. Check for End-of-Life status as this model may be discontinued. Request original datasheets and test reports to ensure compliance with technical specifications before integration into production designs.

Selection Notes

Select this component when multiple regulated outputs are required from a single IC footprint. Ensure the input voltage range of 6.5V to 20V aligns with the system supply. Verify that the I2C interface compatibility exists with the host controller. Consider the thermal performance of the 40-TQFN package relative to the expected load currents and ambient operating conditions.

Part Context

This part belongs to the PowerXR series of professional power management ICs. It integrates switching controllers and an LDO to reduce external component count. The design targets high-density applications where board space is limited. It replaces discrete regulator solutions with a unified digital control architecture.

Replacement Considerations

The product is listed as obsolete. Consult official substitution guides for compatible alternatives such as the XRP7713ILB-F if pin-out and functionality alignment permits. Verify electrical parameters match the original design requirements before transitioning.
