Overview
The XRP7704ILB-1003-F is a quad-output PWM step-down DC-DC controller with an integrated LDO, manufactured by MaxLinear. It operates within a 6.5V to 20V input range and supports output voltages from 0.9V to 5.1V. The device features independent digital pulse width modulation channels with five-coefficient PID control and up to six reconfigurable GPIO pins. It is housed in a 40-TQFN (6x6) package and allows full programming via an I2C interface.
Feature Summary
- Four switching buck controllers with internal FET drivers
- Fully programmable via I2C interface with non-volatile memory
- Independent start-up delay, ramp, and soft-stop control per channel
- Integrated over-temperature, under-voltage lockout, and per-channel protection
Applications
- Multi-rail power distribution systems
- Digital power management solutions requiring I2C control
- Embedded systems with standby power requirements
Procurement Notes
Verify component authenticity due to End-of-Life status. Confirm package integrity and pin alignment against the 40-TQFN specification. Request manufacturer documentation for discontinuance notices and final shipment terms. Ensure compatibility with existing I2C bus configurations before procurement.
Selection Notes
Select this component for applications requiring four independent regulated outputs from a single controller. Verify that the required input voltage falls between 6.5V and 20V. Confirm that the system design can accommodate the 40-TQFN footprint. Evaluate if the built-in LDO meets standby power needs without external components.
Part Context
This part belongs to the XRP7704 series of professional power management ICs. It integrates multiple buck regulators and an LDO into a single solution. The series is designed for high integration, reducing external component count. It utilizes digital control for precise regulation and monitoring capabilities.
Replacement Considerations
No public confirmed substitute part numbers are available. The product is listed as End-of-Life. Designers should evaluate alternative PMICs with similar quad-output capabilities and I2C interfaces.
