Product details
Overview
DA9213-XXFS1-AT from Renesas Electronics is an automotive-grade, four-phase synchronous buck converter PMIC delivering up to 20 A output current for CPU/GPU/DDR rails in ADAS and infotainment systems. It operates from 2.8 V to 5.5 V input, provides 0.3–1.57 V programmable output (±1% static accuracy), and features 3 MHz switching frequency with integrated power switches and remote sensing.
For engineers reviewing the DA9213-XXFS1-AT datasheet, DA9213-XXFS1-AT pinout, DA9213-XXFS1-AT application, or DA9213-XXFS1-AT equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification, dynamic voltage control (DVC) via I²C/SPI, automatic phase shedding, and 66-pin VFBGA 0.5 mm pitch package optimized for point-of-load regulation in space-constrained automotive PCBs.
Technical Context
The DA9213-XXFS1-AT implements a single four-phase buck topology with all phases assigned to Buck A, enabling high-current, low-ripple 20 A output. Its 3 MHz fixed-frequency PWM operation supports compact 0.22 µH inductors and achieves 10 A/µs transient response for multi-core processor load steps.
It integrates dual-mode control (PWM and PFM), ±1% static output voltage accuracy, and programmable soft-start (50–500 µs). Remote sensing at FBAP/FBAN pins compensates for PCB IR drop, while DVC adjusts VOUT dynamically via register writes or dedicated DVS pin-critical for adaptive SoC power management.
