Power management and switching

STMicroelectronics

This 3‑phase inverter board provides a complete motor drive for prototyping high-voltage BLDC/PMSM control. It features a 650V-rated power stage capable of about 300W output and accepts between 50 and 400V dc bus input. An onboard flyback converter generates the necessary 15V and 3.3V supplies for the gate driver and MCU. The board uses single-shunt current sensing and supports both sensorless and sensored FOC or six-step control algorithms out of the box. Standard STM32 debugging and programming tools are supported via an external SWD connector on board (STLINK), and headers are provided for motor feedback. This evaluation kit helps to evaluate the STSPIN32G0602Q in real-world motor control applications.

The STEVAL-3601CV1 demonstrates a smart converter design able to deliver up to 1A output current from a 3.3 to 36V input, with a 5V output voltage. The board features the DCP3601 miniaturized synchronous step-down converter, which implements enhanced peak current control and advanced design circuitry to minimize quiescent current. The board demonstrates how highly efficient conversion can be achieved with just the DCP3601, an inductor, two small capacitors, and two resistors.

 

The board highlights key application benefits made possible by the DCP3601, including high efficiency and small PCB size, and is ideal for power conversion solutions in major appliances, smart metering, industrial 24V BUS conversion and general-purpose wide power supplies.

Power Integrations

The RDR-1016 reference design board from Power Integrations implements a flyback converter which provides a dual isolated output voltage of 12V at 2A, and 5V at 500mA, from a wide input-voltage range of 85V to 265V ac. The power supply is based on the TNY5073K flyback converter, a member of the TinySwitch-5 family of ICs. 

The board achieves peak efficiency of at least 87% at full load with a 230V ac input. Average efficiency across the load range is at least 85%. 

The RDR-1016 conforms to the requirements of the CISPR22B/EN55022B standards for conducted EMI emissions. It is specified for operation at an ambient-temperature range of 0°C to 40°C with free-air convection cooling.

Littelfuse

The LEB-0024 evaluation board for the CPC1601M from Littelfuse includes on-board switches and a mode selector, allowing easy hands-on testing of the relay either manually or via external control signals. 

The kit features manual load switching via built-in tactile push-buttons, external control input pins for driving the relay from a microcontroller or logic, and a slide-switch to select an external supply or load-powered mode. The board includes a test pin to power external components up to 10mW, and over-voltage protection with a transient voltage suppression diode for the relay outputs.

The LEB-0024 board provides a ready-made platform to evaluate the CPC1601M latching and energy-harvesting capabilities.

This evaluation board features TO-247-4L type power software for NCP51152BADR2G and  NCP51152CADR2G gate drivers.

The NCPV51152 isolated single-channel gate driver features 4.5A source and 9A sink current. The gate drive is designed for fast switching to drive power MOSFETs, and SiC MOSFET power switches. 

Short and matched propagation delays are offered. The NCP51152xA provides a split output that controls the rise and fall times individually. The NCP51152xB has the UVLO of the common collector voltage referenced to GND2 to get a true UVLO.

The NCP51152 is available in a 4mm SOIC-8 package and can support isolation voltage up to 3.75kVrms. Another important protection function is independent under-voltage lockout for both-side driver.

Monolithic Power Systems

The EVM54313-BJ-00A evaluation board demonstrates the capabilities of the MPM54313, a triple-output, fully integrated power module which integrates an I2C interface. Each output can support 3A, for a total of 9A. The MPM54313 offers a complete power solution with built-in, power-on and power-off sequencing control, configurable soft-start, compensation, and various protection thresholds.
