XRP7704ILB-1002-F

Overview

The XRP7704ILB-1002-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 range and provides programmable output voltages from 0.9V to 5.1V. The device features independent Digital Pulse Width Modulator (DPWM) channels with five-coefficient PID control and supports I2C interface programming. Switching frequencies are adjustable between 300 kHz and 1.5 MHz. It includes built-in GPIOs, power monitoring, and protection mechanisms such as over-temperature, under-voltage lockout, and per-channel over-current/voltage protection.

Feature Summary

• Fully programmable via I2C interface for configuration and control
• Independent DPWM channels with five-coefficient PID control for precise regulation
• Integrated LDO configurable to 3.3V or 5V for standby power applications
• Complete power monitoring and reporting capabilities with non-volatile memory storage

Applications

• Multi-rail server and storage system power distribution
• Industrial equipment requiring flexible voltage sequencing
• Telecommunications infrastructure power management
• Embedded systems needing compact digital power solutions

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm package integrity and marking consistency against official datasheets. Check for recent Product Change Notices (PCN) regarding manufacturing site or material updates. Ensure compatibility with existing I2C bus configurations and voltage levels before integration into final designs.

Selection Notes

Select this component when multiple regulated outputs are required from a single IC footprint. Ideal for designs needing independent soft-start/stop sequencing and programmable fault handling. Consider thermal performance in high-density layouts due to integrated FET drivers. Verify that the 6.5V minimum input voltage aligns with the system supply rails.

Part Context

Part of the PowerXR family of digital power management ICs designed for high integration. Replaces discrete analog controllers and external compensation networks. Offers software-defined power delivery flexibility compared to fixed-function regulators. Supports advanced diagnostics and remote monitoring via standard communication protocols.

Replacement Considerations

Check for direct pin-compatible alternatives within the same MaxLinear series. Verify functional equivalence if substituting with other quad-buck controllers. Ensure support for similar I2C command sets and PID tuning parameters. Review end-of-life status for legacy designs requiring long-term supply assurance.
