Tổng Quan Sản Phẩm
STEVAL-DPSG474Q is a digital power supply control board based on full pin-count STM32G474QET6. It can control the power stage of converters requiring high pin counting (PFC, DC-DC, DCAC), or can be used to control the dual stage conversion (PFC+DCDC). The STEVAL-DPSG474Q consists of a platform based on STM32G474QE MCU from the STM32G4 family. The STM32G474QE MCU includes the Arm® Cortex®-M4 32-bit RISC core operating at up to 170MHz frequency, a floating-point unit (FPU), a full set of DSP instructions, and high-speed embedded memories (512Kbytes of flash memory and 128Kbytes of SRAM). The device embeds peripherals that allow mathematical/arithmetic function acceleration. The MCU offers: 5 fast 12bit ADCs, 7 comparators, 6 op-amp, 7 DAC chs (3 external and 4 internal), low-power RTC, 32-bit timers, 3 timers dedicated to motor control, 7 general-purpose 16-bit timers, one 16-bit low-power timer, and HRTIM with 184 ps resolution, specifically designed to drive power conversion systems.
