Overview
The DA9213-XXFS1-AT is an automotive-grade, single-channel synchronous buck converter from the DA9213 series. It delivers up to 20A of output current with an input voltage range of 2.8V to 5.5V and an adjustable output voltage between 0.3V and 1.57V. The device operates at a nominal switching frequency of 3MHz and supports I²C and SPI interfaces. It is housed in a VFBGA-66 package (5.8mm x 3.8mm, 0.5mm pitch) and functions within a temperature range of -40°C to +105°C.
Feature Summary
- Dynamic Voltage Control (DVC) for adaptive efficiency optimization based on load conditions
- Integrated power switches eliminating the need for external FETs
- Remote sensing capability for precise point-of-load regulation
- Low-profile components under 1mm height enabling compact system designs
Applications
- Automotive infotainment systems
- Navigation systems requiring high processor currents
- Field Programmable Gate Arrays (FPGAs)
- ARM Cortex-A15/A57 multicore application processors
Procurement Notes
Verify final configuration before ordering as parts become non-cancellable once OTP is finalized. Confirm availability status as supply may be limited or restricted. Ensure compatibility with required interface protocols and thermal management requirements for the specific automotive environment.
Selection Notes
Select this component for applications demanding high current delivery from a single channel within automotive temperature ranges. Consider the 3MHz switching frequency for balancing EMI and component size. Verify that the 20A continuous current rating meets the peak load requirements of the target processor or FPGA without exceeding thermal limits.
Part Context
This part belongs to the DA9213 family of high-efficiency multiphase buck converters designed for automotive sub-PMIC applications. It complements other variants like the DA9214-A and DA9210-A, offering scalable power solutions for complex SoCs. The series emphasizes integration and reliability for demanding automotive electronics.
Replacement Considerations
Consult official substitution lists for equivalent performance. Direct replacements must match the 20A output capability, 2.8V-5.5V input range, and VFBGA-66 package dimensions. Verify AEC-Q100 qualification and operating temperature range compatibility.
