Power management and switching

STMicroelectronics

The X-NUCLEO-DRP1M1 expansion board from STMicroelectronics enables designers to evaluate the features of the TCPP03-M20 USB Type-C® Power Delivery (PD) controller, including the ability to protect the bus- and supply-voltage lines in dual-role power (DRP) applications.

The expansion board can be stacked on top of any STM32 Nucleo-64 board which has a USB PD peripheral embedded in its microcontroller.

The X-NUCLEO-DRP1M1 demonstrates dead battery and sink operations, an integrated ST715PU33R linear regulator supplies the associated STM32 Nucleo development board. It also performs USB Type-C source operations when a compatible external source is connected to the board. In addition, the board supports dual role data functionality for sourcing devices.

The X-NUCLEO-DRP1M1 complies with the USB Type-C and USB PD 3.1 specifications for the standard power range, and is USB-IF certified as a 100 W DRP solution supporting a programmable power supply.

The companion X-CUBE-TCPP software package contains application examples for NUCLEO-G071RB and NUCLEO-G474RE development boards. These can be ported to other development boards that have USB Type-C PD-enabled MCUs.

Vishay

The SiC951EVB-A reference board from Vishay enables a design engineer to evaluate the features and functions of the SiC951 microBRICK® dc-dc regulator module. It also serves as a reference board design for use in applications. 

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 InnoSwitchâ„¢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.
