Getting started with the STEVAL-DPSG474 digital power supply control kit
Introduction
The
STEVAL-DPSG474
STM32G474RE
communication interfaces and allows programming the microcontroller through a standard 20-pin JTAG connector.
The
STM32G474RE
at up to 170 MHz frequency, a floating point unit (FPU), a full set of DSP (digital signal processing) instructions,
and high-speed embedded memories (512 Kbytes of flash memory and 128 Kbytes of SRAM).
The device embeds peripherals that allow the mathematical/arithmetic function acceleration (CORDIC for
trigonometric functions and FMAC unit for filter functions).
The MCU offers five fast 12-bit ADCs (5 Msps), seven ultra-fast comparators, six operational amplifiers, seven
DAC channels (three external and four internal), a low-power RTC, 32-bit timers, three timers dedicated to motor
control, seven general-purpose 16-bit timers, one 16-bit low-power timer, and the high-resolution timer (HRTIM)
with 184 ps resolution, specifically designed to drive power conversion systems.
The main board embeds a standard 64-pin DIN 41612 connector for connection with a power board. It provides
all the PWM control signals, sensing networks, and protection features needed for a wide range of digital power
supply applications.
An external 5 V supply voltage can supply the board either through a dedicated connector or through the main
connector. The adapter board features a configurable user communication (SMBus, CAN, or RS-232) with two
DB9 connectors and the appropriate transceiver ICs, a standard STDC14 14-pin connector, which provides
the SWD interface for debugging and USART communication for user interface (UI), and the standard JTAG
connector for programming.
The board also includes a reset button and a termination resistance between the CAN lines.
You can easily connect the
and dedicated connectors.

Page 5: Dsmps Connector
DSMPS connector DSMPS connector The DSMPS connector is a 64-pin ST standard connector adopted in several power conversion evaluation kits (for example, STEVAL-DPSLLCK1, STEVAL-DPSTPFC1, STEVAL-LLL009V1, etc.), which allows an easy control board connection and a fast microcontroller change. Thanks to this modular approach, you can use the same control board for different applications, or change the microcontroller to evaluate the performances of the latest ST products. -

COMP6_INP STDC14 connector The CN1 connector can be used either to connect a standard ST-LINKV3 dongle, which allows programming the microcontroller and debugging the user application using an SWD connection. It also allows connecting the adapter board included in the STEVAL-DPSG474 kit. -
Page 7: Adapter Board
LEDs The control board embeds three user LEDs that, in ST FW applications, are usually adopted to show the status of the power converter and if any fault occurred. The number of blinks of each LED depends on the final application. - Page 8 UM2997 LEDs Diode Name Color Function Fault LED: it indicates that a nonrecoverable fault occurred (for example, an overcurrent, etc.) FAULT_LED and you have to restart the board. Error LED: it indicates that a recoverable fault occurred (for example, an input undervoltage, ERROR_LED Yellow etc.).
