Power management and switching

Nordic Semiconductor

The nPM2100-EK allows for easy, code-free configuration of the nPM2100 PMIC through the nPM PowerUP application. The kit includes add-on boards and holders for AA, AAA, LR44, and CR2032 batteries for evaluation of different battery combinations. Settings can be configured via a graphical user interface (GUI) and exported as code for implementation in firmware. The board provides access to all PMIC functions including fuel gauge and power-saving modes.

 

STMicroelectronics

The STEVAL-3603BC1 evaluation board demonstrates a synchronous step-down converter design able to deliver up to 3A output current from a 3.3V to 36V input, with a 5V output voltage. The board uses the DCP3603BCMR in the thin SOT23-6L package and shows how efficient conversion can be achieved using the converter, an inductor, two small capacitors, and two resistors. It is suitable for power conversion in major appliances, smart metering, industrial 24V bus conversion, and general-purpose wide Vin power supplies.

The EVLVIPGAN100WP is the STMicroelectronics 100W reference design evaluation board built around the VIPERGAN100WBTR. It implements a complete QR-flyback converter for USB-PD or other isolated 100W supplies with opto-feedback control. The board integrates EMI filtering, surge/overvoltage input protections and optimized thermal layout. Designers can use it to quickly evaluate performance and accelerate design cycles for industrial and telecom power supplies.

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.
