The EVLVIPGAN100PD from STMicroelectronics is a 100 W USB Power Delivery (PD) 3.0 reference design for a USB Type-C® power adapter. 

It is an isolated power supply with a stand-alone USB PD controller. The evaluation board implements, at the primary side, a quasi-resonant flyback converter based on the ST VIPERGAN100, high-voltage flyback converter with optocoupler feedback for voltage regulation and a high-voltage gallium nitride (GaN) power switch. 

The converter combines a high-performance, low-voltage PWM controller chip with a 650 V start-up cell in a single package. The reference design achieves low standby power consumption thanks to the VIPERGAN100’s advanced power management and low quiescent current. 

To reduce the input mains current distortion, a power factor correction circuit based on the L6564 controller IC is used. At the secondary side, to increase system efficiency, rectification is based on the SRK1001 adaptive synchronous rectification controller.

The reference design also includes an STUSB4761 controller, which offers the benefits of a full hardware USB PD stack, allowing for robust, deterministic, and safe negotiation in line with USB PD standards.

The STEVAL-56G3MAI module enables easy evaluation of the VD56G3 1.5 Mpixel monochrome image sensor from STMicroelectronics. The module features a soldered sensor, an M12 lens holder screwed to the board, and a removable lens. The module also has a flex cable to connect to a broad range of embedded processing platforms. 

The module is one of a family of modules for evaluating various products in the ST BrightSense image sensor portfolio. All share the same standard connector and pinout, to enable easy replacement of one image sensor with another in proof-of-concept designs. 

All of the image sensor modules are backed by a comprehensive set of enablement software, drivers and evaluation tools, including drivers for a Linux® operating system. The modules also support GUI software for evaluation when paired with the ST EVK Main board.

The STM32 Nucleo-64 board for the STMicroelectronics STM32U3 series of ultra-low power microcontrollers provides an affordable and flexible way for users to try out new concepts and build prototypes.

The new STM32U3 series implements cutting-edge power-saving innovations which ease the deployment of battery-powered embedded devices, especially in remote locations.

These latest MCUs are aimed at IoT devices that operate for extended periods without maintenance and with the limited energy from a coin cell or ambient solar or thermoelectric source. They take advantage of innovative techniques such as near-threshold design to cut dynamic power consumption, boosting efficiency by a factor of two compared to the previous STM32U5 series of ultra-low power MCUs from ST. 

 The NUCLEO-U385RG-Q board offers Arduino® Uno V3 connectivity support. ST morpho headers allow easy expansion of the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.

The STM32 Nucleo-64 board does not require any separate probe as it integrates the ST-LINK debugger/programmer.

The STM32 Nucleo-64 board is supplied with comprehensive, free STM32 software libraries and examples available with the STM32Cube MCU package.

The X-NUCLEO-53L4A3 from STMicroelectronics is an expansion board for any STM32 Nucleo board equipped with Arduino R3 connectors which enables designers to develop applications using the VL53L4ED short-range time-of-flight (ToF) proximity sensor.

The expansion board is supplied with a cover glass holder in which designers can fit a spacer of 0.25 mm, 0.5 mm, and 1 mm height below the cover glass to simulate a variety of air gaps. A small oval cover glass fitting the sensor is included.

The kit includes:

  • Two different cover glass units to protect the sensor from dust
  • Compatible with STM32 Nucleo development boards
  • Equipped with Arduino® UNO R3 connectors
  • Full system software, including code examples and a graphical user interface

The EVLSTGAP3S6S is a half-bridge evaluation board for evaluating the STGAP3S6S isolated single gate driver from STMicroelectronics.

The STGAP3S6S features a maximum 6 A current capability, rail-to-rail outputs, and optimized under-voltage lockout and desaturation protection thresholds for silicon carbide (SiC) MOSFETS. It is ideal for use in high-power industrial motor drivers.

The gate driver has a single Output pin and a driver line for an external Miller clamp N-channel MOSFET: this optimizes the suppression of positive and negative gate spikes during fast commutations in half-bridge topologies.

Device protection features are connected to the recommended network on the board and can be easily evaluated through the board test points. Dual Input pins allow the selection of signal-polarity control and hardware interlocking protection to avoid cross-conduction in case of controller malfunction.

The gate driver allows negative gate driving, and the onboard isolated dc-dc converters provide an optimized drive voltage for SiC MOSFETs.
