Power management and switching

STMicroelectronics

The STEVAL-PMIC25V1 from STMicroelectronics is a power management IC (PMIC) evaluation board for the highly integrated STPMIC25. This PMIC manages the power requirements of the core, memory and interfaces of the STM32MP2x series microprocessors and other applications microprocessors.

The kit includes a USB dongle, which provides access via I2C interface to the configuration registers of the STPMIC25, where voltage settings, power sequences, protection thresholds and other parameters can be set.

The board includes header connectors for external access to the embedded regulators and switches in the PMIC, as well as internal routing via jumpers to satisfy any physical configuration requirements.

The passive components on the board are chosen for optimal performance across most operating conditions. Three push buttons and digital I/Os allow the engineer to trigger the digital controls of the PMIC.

Power Integrations

The RDK-1002 from Power Integrations is a reference design kit which facilitates development with the InnoSwitch™5-Pro family of flyback switcher ICs. It implements a USB Power Delivery 3.1 extended power range (EPR) power supply supporting loads up to 140 W. It operates from an input-voltage range of 90 V to 265 V ac, and achieves conversion efficiency of up to 95%. It supports variable output voltages in a range from 5 V to 28 V.

The NCD57252 evaluation driver board enables evaluation of the NCD57252, a high-current gate driver which can directly drive two independent IGBTs in any configuration. The driver provides 5 kVrmss of internal galvanic isolation from input to each output and functional isolation between the two output channels. 

Diodes

This demonstration board uses the AL17052, a buck converter IC operating from a universal mains input voltage, to build a cost-effective solution for high-voltage buck converter applications. The AL17052 integrates a 700V MOSFET and can work with a single-winding inductor and very few external components to provide an accurate constant-voltage output and good dynamic performance.

STMicroelectronics

The STEVAL-DIGAFEV1 evaluation board from STMicroelectronics enables designers to evaluate the performance of the TSC1641, a 16-bit, high-precision current and power monitor which has a MIPI I3C/I2C interface.
