Overview
The DA9213-XXFSC-A is an automotive-grade, single-channel synchronous buck converter sub-PMIC from Renesas. It delivers up to 20A of output current with a nominal switching frequency of 3MHz. The device operates with an input voltage range of 2.8V to 5.5V and provides an adjustable output voltage between 0.3V and 1.57V. It features dynamic voltage control (DVC), ±2.0% load transient response, and remote sensing capabilities. The component is housed in a VFBGA-66 package with a 0.5mm pitch.
Feature Summary
- Integrated power switches eliminate the need for external FETs, reducing component count.
- Dynamic Voltage Control (DVC) enables efficient power management for processor cores.
- Remote sensing at the point of load ensures high accuracy under varying loads.
- Low-profile components below 1mm height facilitate compact system designs.
Applications
- Automotive infotainment systems
- Navigation systems requiring high currents
- Field Programmable Gate Arrays (FPGAs)
- ARM Cortex-A15/A57 application processors
Procurement Notes
Verify the specific suffix code against official documentation to confirm exact configuration, as variations exist within the DA9213 series. Confirm availability status directly with the manufacturer or authorized distributors, as supply may be limited. Ensure compatibility with existing PCB layouts regarding the VFBGA-66 package dimensions and thermal requirements before finalizing procurement decisions.
Selection Notes
Select this component for applications demanding high current density and fast transient response in automotive environments. It is suitable for powering core rails of multicore processors where efficiency and size are critical. Consider the 3MHz switching frequency for balancing EMI performance and passive component size. Verify that the required output voltage range falls within the 0.3V to 1.57V specification.
Part Context
The DA9213-XXFSC-A belongs to the DA9213 family of multiphase DC/DC buck converters designed for automotive SoCs. It serves as a sub-PMIC, often paired with a main PMIC to handle high-current core supplies. This family supports various ARM-based processors and FPGAs, offering scalable solutions for modern automotive electronics requiring robust power delivery.
Replacement Considerations
The DA9214-A is a related dual-channel alternative offering 2x 10A outputs. For single-channel needs, verify if other DA9213 variants with different suffixes meet specific electrical or packaging requirements. Cross-reference pinouts and thermal characteristics when considering substitutes.
