DA9214-XXFSC-A

Overview

The DA9214-XXFSC-A is an automotive-grade, dual-channel multiphase DC/DC buck converter sub-PMIC designed for high-power multicore SoCs. It features two independent channels, each delivering up to 10A of output current, scalable to 20A in parallel configurations. The device operates with a 2.8V to 5.5V input voltage range and provides adjustable output voltages from 0.3V to 1.57V. Key electrical parameters include a nominal switching frequency of 3MHz and output voltage accuracy of ±2.5%. It utilizes integrated power switches and supports remote sensing.

Feature Summary

• Dual-channel architecture providing independent or combined high-current outputs for flexible power delivery
• Integrated power switches eliminate the need for external FETs, reducing component count and board space
• Supports dynamic voltage control (DVC) and remote sensing at the point of load for improved transient response
• Automotive-grade qualification ensures reliability across wide temperature ranges

Applications

• Infotainment systems in automotive environments
• Telematics units requiring stable power for connectivity modules
• Advanced Driver Assistance Systems (ADAS) processing units
• Full-scale integrated digital cockpits

Procurement Notes

Verify the specific suffix code against official Renesas documentation to confirm exact pinout, thermal characteristics, and factory configuration. Ensure compatibility with target PCB layout guidelines for VFBGA packages. Confirm AEC-Q100 compliance status for the specific revision intended for automotive deployment. Cross-reference lead times and availability through authorized distributors as supply constraints may apply.

Selection Notes

Select this component when designing power stages for automotive applications requiring dual isolated rails or combined high-current capability. Compare against single-channel alternatives if only one rail is needed to optimize cost. Consider the 3MHz switching frequency for inductor size trade-offs. Evaluate thermal performance requirements based on the VFBGA-42 package dissipation capabilities under maximum load conditions.
