Digital power plug-in module (DP PIM) demo board for dsPIC33AK digital signal controllers

The dsPIC33AK512MPS506 Digital Power Plug-In Module (DP PIM) is compatible with a range of power boards to demonstrate the dsPIC33AK512MPS506 digital signal controller (DSC).

The demonstration board directly plugs into the DM330029 digital power development board, the DV330101 low-power FPC development kit, and the EV84C64A interleaved LLC converter development board.

The DP PIM accesses the dsPIC33AK512 analog inputs, the digital-to-analog converter (DAC) output, the pulse-width modulator (PWM) outputs and the general-purpose input and output (GPIO) ports.

Renesas

The RTDTTP4200W066A 4.2kW bridgeless totem-pole power factor correction evaluation board enables highly efficient single-phase AC/DC conversion using the latest Renesas Gen IV Plus SuperGaN® FET. The TP65H030G4PWS is a diode-free GaN FET bridge with low reverse recovery charge.

Allegro Microsystems

Allegro MicroSystems evaluation boards simplify the evaluation process for its tunnel magnetoresistance (TMR) current sensors. The boards provide test points for convenient access to device pins, allowing for quick measurement and validation without the need for complex test set-ups. 

The CTD455-BB-48B5 board provides a simple way to evaluate the performance of the CT455 XtremeSense™ TMR current sensor. The CT455 on the board senses and translates the magnetic field into a linear analog output voltage. The current sensor achieves a total error output of less than 1% over voltage and temperature. 

Key features:

  • Preset magnetic field range: ±6 mT or ±48 mT
  • Low-noise performance
  • Optimized for high dV/dt applications
  • Less than 300 ns response time
  • 5 V supply voltage
  • Operating-temperature range: -40°C to 125°C
STMicroelectronics

The B-WBA5M-WPAN STM32WBA connectivity expansion board from STMicroelectronics provides a flexible way to evaluate the STM32WBA5MMGH6 module.

The board includes a USB Type-C® connector for power only. It also integrates an M.2 E‑Key connector, turning it into an M.2 E‑Key daughterboard which provides a Bluetooth® interface to a host board that has an M.2 E‑Key host connector. The M.2 E‑Key connector is compatible with the PCI-SIG standard, and provides UART, SPI, I2C, and SAI interfaces for communication with the host.

The B-WBA5M-WPAN board is supported by the STM32CubeWBA software package. 

 

Key features include: 

  • 256 kbit serial EEPROM
  • Accurate MEMS temperature sensor
  • 3D accelerometer and 3D gyroscope
  • User LED
  • User and reset push buttons

STMicroelectronics

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.
