DA9224-XXFT1-AT

Overview

The DA9224-XXFT1-AT is an automotive-grade, single-channel multiphase buck converter optimized for high-current CPU and memory power delivery. It features integrated power FETs and supports up to 20A output current with a switching frequency of 3 MHz. The device operates within a 2.8V to 5.5V input voltage range and provides an adjustable output from 0.3V to 1.57V. Key electrical parameters include a fast transient response of 10A/µs and remote sensing capability. It is housed in a 66-pin TFBGA package with a 0.8mm pitch, designed for -40°C to +105°C operation.

Feature Summary

• Integrated power switches eliminate external component requirements
• Dynamic Voltage Control (DVC) optimizes efficiency across load ranges
• Automatic phase shedding reduces quiescent current at light loads
• Remote sensing ensures precise voltage regulation at the point of load

Applications

• Automotive in-vehicle infotainment systems
• Advanced Driver Assistance Systems (ADAS)
• Navigation and telematics applications
• Multi-core application processor supply rails

Procurement Notes

Verify the specific suffix configuration against the official Renesas datasheet to ensure correct packaging and qualification levels. Confirm that the requested part number matches the exact pinout and thermal requirements for your PCB layout. Check for any recent lifecycle notifications or obsolescence warnings directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single high-current rail is required for automotive processors. Ensure the design accommodates the 0.8mm pitch BGA footprint and utilizes remote sensing traces for accuracy. Compare against the DA9223 if quad-phase performance is needed instead of single-channel high-amperage delivery.

Part Context

This part belongs to the DA922x-A series of PMICs designed specifically for automotive environments. It complements other variants like the DA9223 by offering a single-channel solution tailored for lower pin-count designs while maintaining high efficiency and automotive reliability standards under AEC-Q100 Grade 2 qualification.

Replacement Considerations

The DA9223-XXFTD-A is a related quad-phase variant within the same family. Verify compatibility if substituting, as channel count and current capabilities differ significantly between single and quad-phase architectures.
