Overview
The DA9214-XXFS1 is a dual-channel, two-phase multiphase DC/DC buck converter designed for high-efficiency power delivery. It features an input voltage range of 2.8V to 5.5V and provides an adjustable output voltage from 0.3V to 1.57V. Each channel delivers up to 10A of output current, supporting parallel configurations for higher load demands. The device operates with a nominal switching frequency of 3MHz and maintains output voltage accuracy within ±2.5%. It includes integrated power switches, adjustable soft-start, and remote sensing capabilities, functioning reliably across a temperature range of -40°C to +85°C in a VFBGA-42 package.
Feature Summary
- Dual-channel architecture providing independent or combined power rails for complex system requirements
- Integrated power switches eliminate the need for external FETs, reducing component count and board space
- Dynamic Voltage Control (DVC) enables adaptive supply voltage adjustment based on processor load conditions
- Remote sensing at the point of load ensures precise voltage regulation under varying load currents
Applications
- Multicore System-on-Chips (SoCs)
- Graphics Processing Units (GPUs)
- Field Programmable Gate Arrays (FPGAs)
Procurement Notes
Verify specific ordering suffixes and package variants carefully, as availability may be limited. Confirm that the selected part matches the required pinout and thermal specifications for your design. Check for any recent lifecycle notices or obsolescence warnings directly from Renesas. Ensure compatibility with your existing bill of materials and manufacturing processes before finalizing procurement decisions.
Selection Notes
Select this component when designing systems requiring dual independent power domains with high current density. It is suitable for applications needing fast transient response and high efficiency across wide load ranges. Consider the VFBGA-42 package constraints for PCB layout and thermal management. Evaluate if the 3MHz switching frequency aligns with your EMI requirements and inductor size constraints compared to lower-frequency alternatives.
Part Context
The DA9214 belongs to the DA921x series of professional power management ICs from Renesas. This series targets high-performance computing and graphics applications. It complements other devices like the DA9213 and DA9211, offering scalable solutions for different current and phase requirements within the same ecosystem.
Replacement Considerations
The DA9213-A is a single-channel alternative with higher per-phase current capability. The DA9214-A is the automotive-grade version of this device. Verify functional equivalence and pin compatibility before substitution.
