Overview
The DA9213-XXFSC-AT is an automotive-grade, single-channel synchronous buck converter from the Renesas 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 range of 0.3V to 1.57V. The device features a nominal switching frequency of 3MHz and operates within a temperature range of -40°C to +105°C. It utilizes a BGA package with a 0.5mm pitch. Key functional attributes include dynamic voltage control (DVC), remote sensing capabilities, and support for I2C and SPI interfaces.
Feature Summary
- Dynamic Voltage Control (DVC) enables adaptive output voltage adjustment based on load conditions to optimize efficiency.
- Remote sensing functionality ensures high accuracy at the point of load by compensating for PCB trace voltage drops.
- Integrated power switches eliminate the need for external FETs or Schottky diodes, reducing component count.
Applications
- Automotive infotainment systems
- Automotive navigation systems
- Field Programmable Gate Arrays (FPGAs)
- Xilinx Zynq Ultrascale+ MPSoC platforms
Procurement Notes
Verify the specific suffix configuration against official Renesas documentation before ordering, as custom OTP programming may render the part non-cancellable. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the selected package variant matches the required PCB footprint and thermal specifications for the target application design.
Selection Notes
Select this component for applications requiring high current delivery in compact automotive environments. The 20A capability supports high-performance processors like ARM Cortex-A15/A57 families. Consider the BGA package size and thermal dissipation requirements when designing the PCB layout. Verify interface compatibility with the host controller for I2C or SPI communication protocols.
Part Context
This part belongs to the DA9213 family of high-efficiency multi-phase buck converters designed for automotive grade reliability. It is engineered to power core rails for application processors and GPUs in demanding automotive infotainment and navigation systems. The series emphasizes small form factor solutions with low output ripple and fast transient response.
Replacement Considerations
Consult official Renesas substitution guides for verified alternatives. Generic industry equivalents are not confirmed substitutes due to specific automotive qualification and pinout differences.
